What is an electromagnetic wave?

Back

An electromagnetic wave is a type of wave that consists of oscillating electric and magnetic fields and travels through space at the speed of light.

Front

What is 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 is wavelength?

Back

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

Front

What is frequency?

Back

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

Front

How is the speed of a wave calculated?

Back

The speed of a wave is calculated using the formula: Speed = Wavelength x Frequency.

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

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 unit of measurement for frequency?

Back

The unit of measurement for frequency is Hertz (Hz).

Front

What does a higher amplitude indicate about a wave?

Back

A higher amplitude indicates that the wave carries more energy.
