Parts of a Wave

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, representing the maximum displacement of the wave from its rest position.

Front

What is a trough in a wave?

Back

A trough is the lowest point of a wave, representing the minimum displacement of the wave from its rest position.

Front

How is amplitude measured?

Back

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

Front

What is the relationship between wavelength and frequency?

Back

Wavelength and frequency are inversely related; as the wavelength increases, the frequency decreases, and vice versa.

Front

What does the term 'rest position' refer to in wave mechanics?

Back

The rest position is the equilibrium position of the medium through which the wave travels, where there is no disturbance.

Front

What is the formula for calculating wave speed?

Back

Wave speed (v) can be calculated using the formula v = frequency (f) × wavelength (λ).

Front

What is the significance of wave frequency?

Back

Frequency indicates how many waves pass a given point in one second, measured in hertz (Hz).

Front

What is the difference between transverse and longitudinal waves?

Back

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