What is the valley of a wave?

Back

The valley of a wave, also known as the trough, is the lowest point of the wave, where the wave's displacement is at its minimum.

Front

What is frequency in the context of waves?

Back

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

Front

What is wavelength?

Back

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

Front

How does wavelength affect frequency?

Back

When the wavelength is longer, the frequency is lower; they are inversely related.

Front

What is amplitude in a wave?

Back

Amplitude is the maximum displacement of points on a wave from its rest position, indicating the wave's energy.

Front

What type of sound is produced by a wave with low frequency?

Back

A wave with low frequency produces a quiet, low-pitched sound.

Front

What is the relationship between amplitude and sound volume?

Back

Higher amplitude waves produce louder sounds, while lower amplitude waves produce quieter sounds.

Front

What is the difference between a peak and a valley in a wave?

Back

A peak is the highest point of a wave, while a valley (or trough) is the lowest point.

Front

What happens to sound pitch as frequency increases?

Back

As frequency increases, the pitch of the sound becomes higher.

Front

What is the formula for calculating wave speed?

Back

Wave speed = frequency × wavelength.
