What color of the rainbow has the longest wavelength?

• red

• blue

• green

• violet

The highest point of a wave is known as the ___________

• wavelength

• crest

the height or depth of a wave that determines how much ENERGY the wave carries. In a sound wave, it is also synonymous with how much volume the wave carries.

• wavelength

• compression

• amplitude

What type of wave is a light wave?

• 10 waves per second

• 3 waves per second

• 6 waves per second

• 2 waves per second

How is an electromagnetic wave different from a mechanical wave?

• An electromagnetic wave travels slower than a mechanical wave.

• An electromagnetic wave has a larger amplitude than a mechanical wave.

• An electromagnetic wave can travel through a vacuum, but a mechanical wave cannot.

• An electromagnetic wave has no wavelength, but a mechanical wave has a wavelength.
