Unit #9 - Waves Review

Front

What are rarefactions in longitudinal waves?

Back

Rarefactions are the parts of a longitudinal wave where the coils are spread apart.

Front

What does a shorter wavelength indicate about a wave's energy?

Back

A shorter wavelength indicates that the wave has more energy.

Front

Which electromagnetic wave has the highest energy and shortest wavelength?

Back

Gamma rays have the highest energy and shortest wavelength of all electromagnetic waves.

Front

What causes the change in pitch of a sound as a source moves towards or away from an observer?

Back

The change in pitch is caused by a change in the frequency of the sound wave.

Front

What type of wave does sound travel in?

Back

Sound travels in longitudinal waves.

Front

Define amplitude in the context of waves.

Back

Amplitude is the maximum extent of a vibration or oscillation, measured from the position of equilibrium.

Front

What is the relationship between frequency and energy in waves?

Back

Higher frequency waves carry more energy than lower frequency waves.

Front

What are compressions in longitudinal waves?

Back

Compressions are the parts of a longitudinal wave where the coils are close together.

Front

How does wavelength affect the speed of a wave?

Back

In a given medium, the speed of a wave is constant; however, wavelength and frequency are inversely related.

Front

What is the difference between transverse and longitudinal waves?

Back

In transverse waves, the particle displacement is perpendicular to the direction of wave propagation, while in longitudinal waves, it is parallel.
