Which type of wave transfers energy through compressions and rarefactions in the material through which the wave travels.

• longitudinal Waves

• Transverse Waves

• Ocean Waves

• Sound Waves

what is a compression?

• The region of the wave in which the material through the wave is spread apart

• The region of the wave in which the material through the wave is eating a sandwich

• the region of the wave in which the material through which the wave is pressed together.

• I don't care

True or False infrared waves are longer than Radio waves

• True

• False

What is the medium of a wave

• Matter in which wave energy travels through

• Matter in which wave energy avoids

• Matter that is in the center of a wave
