definition and words of waves and EM

Which of the following describes what happens to light/ or presents an example of when it is reflected off of a smooth surface?

• The reflected ray bounces off the surface at the same angle as the incident ray.

• The light is scattered every where.

• You can see yourself in a mirror if you are standing near it.

• Explains why we are able to see a piece of paper from many angles, even when we are not close to it.

• The reflected ray bounces off the surface at the same angle as the incident ray.

• The light is scattered every where.

• You can see yourself in a mirror if you are standing near it.

• Explains why we are able to see a piece of paper from many angles, even when we are not close to it.

Why would a wave change direction?

• Because it went from one medium to another.

• Because the amplitude was too large.

• Because the frequency was too small.

• Because the wavelength remained the same.

What is different about the speed of sound waves vs. the speed of light?

• sound waves are the FASTEST in solids (high density), while light waves are the FASTEST in gas (or no molecules)

• sound waves are the FASTEST in gas (low density), while light waves are the FASTEST in solids

• Both have the same speed all the time

• Both are the FASTEST in the air or gas (low density)
