Parts and properties of waves test review

Front

What is a wave?

Back

A wave is a disturbance that transfers energy from one place to another without transferring matter.

Front

What are the two main types of waves?

Back

The two main types of waves are mechanical waves (which require a medium) and electromagnetic waves (which do not require a medium).

Front

What is amplitude in a wave?

Back

Amplitude is the maximum height of a wave from its rest position, indicating the energy of the wave.

Front

What is wavelength?

Back

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

Front

What is frequency?

Back

Frequency is the number of waves that pass a given point in one second, measured in Hertz (Hz).

Front

What is the relationship between amplitude and energy in a wave?

Back

Higher amplitude means more energy; therefore, a wave with a larger amplitude carries more energy.

Front

What are compressions in a longitudinal wave?

Back

Compressions are regions in a longitudinal wave where particles are close together.

Front

What are rarefactions in a longitudinal wave?

Back

Rarefactions are regions in a longitudinal wave where particles are spread apart.

Front

How does the amplitude of a sound wave affect its loudness?

Back

The higher the amplitude of a sound wave, the louder the sound; lower amplitude results in a quieter sound.

Front

What is the formula to calculate wave speed?

Back

Wave speed = frequency × wavelength.
