Light waves review

Front

What is the definition of wavelength?

Back

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

Front

What does the term 'frequency' refer to in wave physics?

Back

Frequency is the number of waves that pass a point in a certain amount of time, usually measured in Hertz (Hz).

Front

What is amplitude in the context of waves?

Back

Amplitude is the maximum distance that points on a wave move from their rest position, indicating the wave's energy.

Front

What is a peak in a wave diagram?

Back

A peak is the highest point of a wave, representing the maximum amplitude.

Front

What is a valley in a wave diagram?

Back

A valley is the lowest point of a wave, opposite to the peak.

Front

How is wavelength measured?

Back

Wavelength is measured in meters (m) and can be calculated as the speed of the wave divided by its frequency.

Front

What is the relationship between frequency and wavelength?

Back

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

Front

What is the formula to calculate wave speed?

Back

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

Front

What is the significance of the amplitude of a wave?

Back

The amplitude of a wave indicates its energy; higher amplitude means more energy.

Front

What happens to the frequency of a wave if the wavelength is halved?

Back

If the wavelength is halved, the frequency doubles, assuming wave speed remains constant.
