Mechanical Waves Practice Test

Front

What is the relationship between frequency and period of a wave?

Back

They are inversely proportional.

Front

What are the spaced out sections of a wave called?

Back

Rarefactions.

Front

In a transverse wave, how do particles of the medium move?

Back

Perpendicular to the direction of wave travel.

Front

What happens when two waves with different frequencies interfere?

Back

They create a wave with a varying amplitude over time.

Front

Why can't sound travel through a vacuum?

Back

Vacuum lacks particles to transmit vibrations.

Front

Define frequency in the context of waves.

Back

Frequency is the number of waves that pass a point in one second.

Front

What is the unit of frequency?

Back

Hertz (Hz).

Front

Define wavelength.

Back

Wavelength is the distance between two consecutive points in phase on a wave.

Front

What is a compression in a longitudinal wave?

Back

A region where particles are close together.

Front

What is a reflection in wave behavior?

Back

Reflection is when a wave bounces back after hitting a barrier.
