Waves, Energy, and Information

Mechanical waves are created when a source of energy causes a medium to

• move

• compress

• expand

• vibrate

Waves that move the particles of the medium parallel to the direction in which the waves are traveling are called

• longitudinal waves.

• transverse waves.

• surface waves.

• combination waves.

The distance between two corresponding parts of a wave is the wave’s

• amplitude.

• wavelength.

• frequency.

• speed.

The maximum distance that the particles of a medium move from the rest position is the

• amplitude of the wave.

• wavelength of the wave.

• frequency of the wave.

• speed of the wave.
