A ray of light impinges on a mirror at 35 degrees a second mirror is fastened at 90 degrees to the first. After striking both mirrors at what angle relative to the incoming ray is the outgoing ray?
Zero degrees. The ray will leave the two mirrors along a path parallel to the one it came in on. This is the principle of the corner reflector, which is often used as a radar target. Note that the corner reflector uses three reflecting surfaces (that are set up at 90o from each other) instead of the two like are being used here. Wikipedia has a really great drawing that illustrates this two-dimentional problem very nicely. A second link is provided to the article on the corner reflector and the 3-D aspects. == ==
Has a reflecting surface that curves outward?

When an object reflects light does it gain or lose energy?
That would depend on whether the object was active or passive. A passive reflector would gain some energy from the photons during the collision / interaction. An active reflector would first gain some energy then lose more as it pumps energy into the photons, boosting them. Although, at present, I can't think of an example of an active reflector of light, an example concept would be the flipper in a pinball game.
What two types antenna used for terrestrial microwave communication?
Virtually all terrestrial microwave communication is point-to-point, using parabolic reflector antennas. A small percentage uses yagi, helical, corner reflector, or flat-plate reflector antennas. Essentially no "omnidirectional" antennas are used in microwave.

Can you replace reflector lamps with led lamps?
Yes, you can definitely replace reflector lampes with LED reflector lamps. I got a Lighting Ever LED reflector before, so no problem I think.
What is a sentence for the word reflector?

Name the type of a reflector with a smooth surface?
A reflector with a smooth surface is typically known as a specular reflector. This type of reflector reflects light in a single, predictable direction without scattering or diffusing it.
What are the lenses called in a reflector telescope?
In a reflector telescope, the primary mirror reflects and focuses light to the eyepiece. There are no lenses in the optical path of a reflector telescope.
