What is the definition of amplitude in a wave?

Back

Amplitude is the maximum distance that a point on a wave moves from its rest position. It is a measure of the wave's energy.

Front

What is a crest in a wave?

Back

The crest is the highest point of a wave.

Front

What is a trough in a wave?

Back

The trough is the lowest point of a wave.

Front

What is wavelength?

Back

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

Front

How does frequency relate to wavelength?

Back

As frequency increases, wavelength decreases, and vice versa, assuming wave speed is constant.

Front

What is the formula for wave speed?

Back

Wave speed = frequency × wavelength.

Front

What is the relationship between frequency and energy in waves?

Back

Higher frequency waves carry more energy than lower frequency waves.

Front

What is the unit of frequency?

Back

The unit of frequency is Hertz (Hz), which represents cycles per second.

Front

What happens to the wavelength when the frequency of a wave increases?

Back

The wavelength decreases.

Front

What is the difference between transverse and longitudinal waves?

Back

In transverse waves, the particle movement is perpendicular to the direction of wave travel, while in longitudinal waves, the particle movement is parallel to the direction of wave travel.
