Light & waves review

Front

What is amplitude in a wave?

Back

Amplitude is the maximum distance that a wave's particles move from their rest position. It is a measure of the wave's energy.

Front

What do all waves carry?

Back

All waves carry energy.

Front

What is the medium in the context of waves?

Back

The medium is the material through which a wave travels, such as air, water, or solid substances.

Front

What is wavelength?

Back

Wavelength is the distance between two consecutive crests or troughs in a wave.

Front

How is wavelength measured?

Back

Wavelength is measured from crest to crest or trough to trough.

Front

What is frequency in relation to waves?

Back

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

Front

What is the relationship between frequency and wavelength?

Back

Frequency and wavelength are inversely related; as frequency increases, wavelength decreases.

Front

What is a transverse wave?

Back

A transverse wave is a wave in which the particles of the medium move perpendicular to the direction of the wave's travel.

Front

What is a longitudinal wave?

Back

A longitudinal wave is a wave in which the particles of the medium move parallel to the direction of the wave's travel.

Front

What is the speed of a wave?

Back

The speed of a wave is the distance it travels in a given amount of time, calculated as speed = wavelength × frequency.
