Waves Test Review-Fall 2024

Front

What is the fastest medium for sound waves?

Back

Sound waves travel fastest in gases at higher temperatures. For example, sound travels fastest in gas at 100°C.

Front

What is the Doppler Effect?

Back

The Doppler Effect is the change in pitch of a sound as the source moves toward or away from an observer. The pitch decreases as the source moves away.

Front

What is a transverse wave?

Back

A transverse wave is a wave where the medium's vibration is perpendicular to the direction of the wave's travel. An example is light waves.

Front

What do transverse and longitudinal waves have in common?

Back

Both types of waves transfer energy through a medium.

Front

What is the visible light spectrum?

Back

The visible light spectrum ranges between infrared rays and ultraviolet rays.

Front

How does temperature affect the speed of sound in gases?

Back

The speed of sound increases with an increase in temperature in gases.

Front

What is an example of a longitudinal wave?

Back

Sound waves traveling through air are an example of longitudinal waves.

Front

What happens to the pitch of a sound as the source moves away from an observer?

Back

The pitch of the sound decreases as the source moves away.

Front

What is the difference between transverse and longitudinal waves?

Back

In transverse waves, the medium moves perpendicular to the wave direction, while in longitudinal waves, the medium moves parallel to the wave direction.

Front

What are compressions and rarefactions?

Back

Compressions are regions of high pressure in a longitudinal wave, while rarefactions are regions of low pressure.
