What else can I help you with?
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?
A convex reflector.
What are common phrases using the word corner?
out of the corner of my eye just around the corner cutting corners have a corner on the market down on the corner at the corner tap/bar/store/gas station on the corner at the corner remote corner of the world backed into a corner in a corner of my mind painted himself into a corner
Is it 'round the corner' or 'around the corner'?
around the corner.
Are monitors measured side to side or corner to corner?
Corner to corner just like a T V.
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.
Is drywall a reflector?
Yes, drywall is a light reflector.

Palmyra Reflector was created in 1829.
When did Palmyra Reflector end?
Palmyra Reflector ended in 1831.
When was Reflector - newspaper - created?

What is the Off-axis gain of cassegrain antenna?
The off-axis gain of a Cassegrain antenna refers to the antenna's ability to receive or transmit signals effectively when the signal source is not aligned with the main axis of the antenna. This gain is typically lower than the maximum gain achieved when the source is directly in line with the antenna's focus. The design of the Cassegrain antenna, which includes a parabolic reflector and a secondary hyperbolic reflector, helps maintain reasonable performance off-axis, but the gain will vary based on the angle and distance from the boresight. Off-axis gain is an important consideration in applications like satellite communication, where signals may come from various directions.
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?
Bicycles need a reflector on the spokes of the wheels.
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.
