Waves

Front

What is the definition of amplitude in the context of waves?

Back

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

Front

What is the crest of a wave?

Back

The crest is the highest point of a wave.

Front

What is the trough of a wave?

Back

The trough is the lowest point of a wave.

Front

How is wavelength defined in wave physics?

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 the relationship between frequency and wavelength?

Back

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

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 does frequency measure in a wave?

Back

Frequency measures the number of complete wave cycles that pass a point in a given time period, usually expressed 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 particle displacement is parallel to the direction of wave propagation.

Front

What is a wave period?

Back

The wave period is the time it takes for one complete wave cycle to pass a given point.

Front

How can you determine the amplitude of a wave from a graph?

Back

The amplitude can be determined by measuring the vertical distance from the rest position to the crest or trough of the wave.
