What type of surfaces are good radiators of heat?
Dull black surfaces they are also best at absorbing it as well. [Shiny and silvery or white surfaces are poor radiators and absorbers of heat. However they are very good in reflecting heat radiation.]
What are the best absorbers of thermal radiation?
Black, dull surfaces are the best absorbers of thermal radiation because the heat doesn't reflect off it unlike shiny surfaces.
3 things that must happen before seeing an object?
You must have reflection upon you. For example a mirror is an object that can reflect on yourself.Most of the time when you see yourself in the mirror but not always. Mirrors can also show things from different directions as well. Mirrors are shiny surfaces that reflect off light. When you hold a mirror, it can show things behind you that you never thought was there.
Objects that do not reflect light well?
Dark colors, especially flat black do not reflect light well. Carbon Nanotubes are considered the worst for reflecting light.
Do mirrors reflect all forms of electromagnetic radiation and if yes or no why?
The answer is "not all". Mirrors of various types reflect electromagnetic radiation, but only in given frequencies depending on the materials from which the mirror is made. Mirrored glass or metal can reflect heat as well as light, but some absorption occurs. Radio waves and microwaves also impart energy rather than reflect, and gamma rays could either penetrate into the mirror or pass completely through.
Why echo is not produced in many places?
Some surfaces reflect sound well, others don't.
Can sound travel around corner?
Sound certainly can travel around corners. Sound can also travel through hard surfaces like walls and bathroom surfaces as well.
Do evergreens help to cancel out noise?
Evergreens do not reflect noise well so they do act as a sound buffer.
Does a rough surface reflect light in many directions?
Highly polished, shiny surfaces reflect light the best as they are REFLECTive. White or bright surfaces also reflect light well. Dull, Matt surfaces are the worst reflecters of light
What property of dark surfaces enable them to absorb heat radiation?
"dark" implies that the object does not reflect light very well - thus it must be absorbing radiation.
What types of surface reflect well?
Any surface with a reflective property such as mirrored glass, tinfoil, and water.
What types of surfaces can I place the Weber Portable Gas Grill on without the surfaces burning or overheating?
It should only be kept on cement or dirt when being used, wood is okay as well.
Why is it so quiet after a snowstorm?
Snow does not reflect sound well, it absorbs it. So everything you would normally hear after is muffled.

What kind of surfaces reflect sound well?
We will find surfaces that are hard and flat to be the best reflectors of sound. To understand why, we need to review a couple of things about sound. Sound is mechanical energy. The source of the sound will put the sound (mechanical) energy into the medium through which that sound is going to travel. This causes some movement in the medium through which the sound is propagating. Surfaces that reflect sound best will not absorb the sound energy by moving. These surfaces will resist any movement and will thus not take any energy from the sound wave. This said, we'd expect a foam rubber wall will reflect far less sound energy than a concrete wall. Also, a wall that is flat will cause less scattering, which is a distributed redirection of the sound. A flat wall will allow sound to be reflected directly back toward the source (for sound arriving at a right angle to the wall). A wall that is made of cemented river stones, which are rounded, will scatter some of the sound energy and be less as good a reflector of that sound compared to a flat, smooth concrete wall.

How many surface waves are there?
There is Two types of surface waves :)
