Multiple Choice

The diagram shows the magnetic spectrum. Which statement best compares a gamma ray to

a radio wave?

• A gamma ray has more energy than a radio

  wave because it has a longer wavelength and a

  lower frequency.

• A gamma ray has more energy than a radio

  wave because it has a shorter wavelength and a

  higher frequency.

• A gamma ray has more energy than a radio

  wave because it has a shorter wavelength and a

  lower frequency.

Multiple Choice

Mrs.Lewis places a stick in a pond. When she looked down at the stick, it appeared to be broken at the point where the stick entered the water. This was caused by:

• reflection of light from the water

• absorption of light waves by the stick

• refraction of light waves passing from air into water

• diffraction of light waves around the stick

Multiple Choice

As light travels through air and strikes water, which picture shows what happens to the light ray?

Multiple Choice

The picture below shows a diagram of light rays as they travel through a type of telescope. What happens to the light at point X?

• The light hits a mirror and is absorbed, and then it is emitted at a different wavelength.

• The light hits a mirror and scatters into multiple beams of different colors.

• The light hits a lens and reflects at the same angle it hit the lens.

• The light hits a lens and refracts, changing the angle of the light.

Multiple Choice

Which diagram shows light rays being reflected by the mirror?
