Intro to Waves starter

Front

What is the definition of amplitude in a wave?

Back

Amplitude is the maximum distance that points on a wave, such as the crest or trough, move from their rest position.

Front

What does wavelength represent in a wave?

Back

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

Front

What is a crest in a wave?

Back

A crest is the highest point of a wave.

Front

What is a trough in a wave?

Back

A trough is the lowest point of a wave.

Front

What is the relationship between frequency and wavelength?

Back

Frequency and wavelength are inversely related; as the frequency of a wave increases, its wavelength decreases.

Front

What does it mean when we say a wave carries energy?

Back

A wave carries energy through the medium it travels in, but it does not carry matter.

Front

How is the amplitude of a wave measured?

Back

Amplitude is measured from the rest position to the crest or trough.

Front

What is the formula for calculating wave speed?

Back

Wave speed = frequency × wavelength.

Front

What is the significance of the wave's frequency?

Back

Frequency indicates how many waves pass a point in one second and is measured in Hertz (Hz).

Front

What happens to the energy of a wave as its amplitude increases?

Back

As the amplitude of a wave increases, the energy it carries also increases.
