Amplify Waves, Energy, 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.

Why do you see lightning from a distant storm before you hear thunder?

• The thunder is produced after the lightning.

• Your eyes react faster than your ears.

• Light travels faster than sound.

• Sound travels faster than light.

In a longitudinal wave moving along a spring, areas where the coils are farthest apart are called ......

• compression

• rarefaction

• crest

• trough

In transverse waves, the particles of the medium move at right angles to the direction in which the wave is traveling.

• True

• False

Waves that require a medium through which to travel are called electromagnetic waves.

• True

• False
