CFA #4 - Waves

What do all waves have in common? (Please select the two correct answers)

• A. Travel through a medium

• B. Transfer some sort of energy

• C. Travel through a vacuum

• D. Have a back and forth pattern

Please match the wave to its definition:

• a wave of electricity and magnetism that can travel through a medium or empty space

• Electromagnetic Wave

• a wave that travels as a longitudinal wave and can usually be heard

• Transverse Wave

• a wave in which the movement of the wave's medium is perpendicular to the movement of the wave traveling through the medium

• Sound Wave

• a wave in which the wave's medium is compressed in the same direction as the movement of the wave, also called a longitudinal wave

• Compression Wave
