Waves Test Review

Front

In which medium do EM waves travel the slowest?

Back

Solid

Front

A sound wave is traveling through a cave at a speed of 350 meters per second. If the wavelength of the sound wave is 3 meters, what is the frequency of the sound wave?

Back

116.67 Hz

Front

When the frequency of a wave increases, what happens to the wavelength?

Back

The wavelength decreases.

Front

What is the part of the wave where the particles are close together called?

Back

Compression

Front

A boat is drifting on a lake, and the waves are moving at a speed of 15 meters per second. If the frequency of the waves is 2.5 Hz, what is the wavelength of the lake waves?

Back

6 m

Front

What is the formula to calculate the speed of a wave?

Back

Speed = Frequency × Wavelength

Front

Define wavelength in the context of waves.

Back

Wavelength is the distance between two consecutive points in phase on a wave, such as crest to crest or trough to trough.

Front

What happens to the amplitude of a wave when energy is added?

Back

The amplitude increases.

Front

What is the difference between transverse and longitudinal waves?

Back

Transverse waves have oscillations perpendicular to the direction of wave travel, while longitudinal waves have oscillations parallel to the direction of wave travel.

Front

What is a rarefaction in a longitudinal wave?

Back

A rarefaction is the part of the wave where the particles are spread apart.
