Image safety reflector.jpg thumb 200px right Star shaped safety reflector with string and safety pin A safety reflector or pedestrian s reflector is a retroreflector intended for pedestrian s, running runners , bicyclist s, motorcyclist s, and vehicle s. A safety reflector is similar to reflective stripes that can be found on safety vest s and clothing worn by road workers and rescue workers. They are sometimes erroneously called luminous badges or luminous tags, but this is incorrect as they do not themselves produce light, but only reflect it. A safety reflector helps to make a person or vehicle visible to other people and vehicles on the road up to three times further away than without a reflector, since it reflects light from headlight s of an oncoming vehicle. Safety reflectors are especially useful in rural areas where there are no streetlight s.

The bicycle reflector or prism reflector is a common safety device found on the rear, front and wheels of bicycles. It uses the principle of retroreflection to alert another road user of the bicycle s presence on the road. The reflector is usually manufactured in the form of a moulded tile of transparent plastic. The outside surface is smooth, allowing light, such as from a car s headlights, to enter. The rear surface of the tile takes the form of an array of angled micro prisms or spherical beads. The light striking the rear, inside surface of the prisms or beads, does so at an angle greater than the critical angle thus it undergoes total internal reflection . Due to the orientation of the other inside surfaces, any light internally reflecting is directed back out the front of the reflector in the direction it came from. This alerts the person close to the light source, e.g. the driver of the vehicle, to the presence of the cyclist. ref Hyperphysics.phy astr.gsu.edu ref ref Complete physics, Stephen Pople 1999 ref References reflist Bike equipment DEFAULTSORT Bicycle Reflector Category Bicycle parts Reflector Category Safety equipment ... more details

It is designed to enclose an article of food on all but one side, to cause it to bake by capturing radiant heat from an open fire, and reflecting the heat towards the food. In its simplest form, a reflector oven is simply a box or collar that partially surrounds the food, with an open side that faces the heat source, which is generally either a hearth fire or a portable stove , depending on the situation in which the food is being prepared. In Colonial America this method of baking meat, fowl, quick bread, or pastries, was a very popular method for hearth cooking. A reflector oven that uses the Sun as its primary heat source is known as a solar cooker . A Dutch oven , was another popular method of baking while using an open fire or a fire in a hearth. The Dutch oven, unlike the tin kitchen, is made of iron, and would collect and consentrate the heat of coals placed beneath and on top of the oven, while preventing the coals from direct contact with the food, and isolating smoke from the fire from the baking food.

A route reflector RR is a network routing component. It offers an alternative to the logical full mesh requirement of internal border gateway protocol IBGP . An RR acts as a focal point for IBGP sessions. The purpose of the RR is concentration. Multiple BGP routers can peer with a central point, the RR acting as a route reflector server rather than peer with every other router in a full mesh. All the other IBGP routers become route reflector clients. This approach, similar to OSPF s DR BDR feature, provides large networks with added IBGP scalability. In a fully meshed IBGP network of 10 routers, 100 individual statements spread throughout all routers in the topology are needed just to define the remote Autonomous system Internet AS of each peer this quickly becomes a headache to administer. A RR topology could cut these 100 statements down to 20, offering a viable solution for the larger networks administered by ISPs. A route reflector is a single point of failure, therefore at least a second route reflector should be configured in order to provide redundancy. Rules RR servers propagate routes inside the Autonomous system Internet AS based on the following rules If a route is received from nonclient peer, reflect to clients only. If a route is received from a client peer, reflect to all nonclient peers and also to client peers, except the originator of the route. If a route is received from an EBGP peer, reflect to all client and nonclient peers.

Unreferenced date February 2011 A neutron reflector is any material that reflects neutron s. This refers to elastic scattering rather than to a specular reflection . The material may be graphite , beryllium , steel , and tungsten carbide , or other materials. A neutron reflector can make an otherwise subcritical mass of fissile material critical, or increase the amount of nuclear fission that a critical mass critical or supercritical mass will undergo. An example of this is the Demon core Demon Core , a subcritical plutonium Pit nuclear weapon pit that went Critical mass critical in two separate fatal incidents when the pit s surface was momentarily surrounded by too much neutron reflective material. Nuclear reactors In a uranium graphite chain reacting pile, the critical mass critical size may be considerably reduced by surrounding the pile with a layer of graphite, since such an envelope reflects many neutrons back into the pile. To obtain a 30 year life span, the SSTAR nuclear reactor design calls for a moveable neutron reflector to be placed over the column of fuel. The reflector s slow downward travel over the column would cause the fuel to be burned from the top of the column to the bottom. A reflector made of a light material like graphite or beryllium will also serve as a neutron moderator reducing neutron kinetic energy, while a heavy material like lead or lead bismuth eutectic will have less effect on neutron velocity. Nuclear weapons A similar envelope can be used to reduce the critical size of a nuclear weapon , but here the envelope has an additional role its very inertia delays the expansion of the reacting material. For this reason such an envelope is often ... system. The primary stage of a modern thermonuclear weapon may use a lightweight beryllium reflector ....

Typical brightness fluctuations do not exceed 0.1 magnitudes. The brightest rotating ellipsoidal variable is Spica Virginis . References Samus N.N., Durlevich O.V., et al.

Image Corner reflector.svg thumb Working principle of a corner reflector A corner reflector is a retroreflector consisting of three mutually perpendicular, intersecting flat surfaces, which reflects wave s back directly towards the source, but shifted Translation geometry translated . The three intersecting surfaces often have square shapes. Radar corner reflectors made of metal are used to reflect radio waves from radar sets. Optical corner reflectors, called corner cubes , made of three sided glass prisms, are used in surveying. The term is also used for a corner reflector antenna , consisting of two flat metal surfaces at a right angle, with a dipole antenna in front of them. How it works The incoming ray is reflected three times, once by each surface, which results in a reversal of direction. To see this, the three corresponding normal vectors of the corner s perpendicular sides can be considered to form a basis linear algebra basis a rectangular coordinate system x , y , z in which ... , c to a , b , c to a , b , c and it leaves the corner reflector with all three components of direction ... screens.

File Radiator Reflector installation process composite.jpeg thumb Radiator reflector panels being installed behind a domestic radiator A radiator reflector is a thin sheet or foil applied to the wall behind, and closely spaced from, a domestic heating radiator heating radiator . The intention is to reduce heat losses into the wall, and thus to outside the building. This increases the effective heating power of the radiator and so reduces fuel expenditure. Although the foils are termed reflectors , they do not have much effect on thermal radiation radiated heat or its reflection. As radiators work at a relatively low temperature, the Stefan Boltzmann law ref group note The Stefan Boltzmann law states that the effectiveness of a thermal radiator is proportional to the fourth power of its absolute temperature . A hot water radiator at convert 77 C K has only 1 4 the emissive power of a stove at convert 220 C K , or 1 16 that of a radiant element at convert 427 C K ref means that they are weak radiators of heat. Most heat from a domestic radiator is as convection currents of heated air. Where a reflector foil has some insulating ability against thermal conduction conduction i.e. losses through the wall , it may have some useful effect. This is most pronounced when the wall itself has poor insulation performance in a wall constructed to modern standards of insulation, even this effect ... reflector of ordinary aluminium Tin foil kitchen foil is useful.
