What is wavelength?

Back

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

Front

How does wavelength affect wave properties?

Back

Longer wavelengths result in lower frequency and lower energy, while shorter wavelengths result in higher frequency and higher energy.

Front

What is the relationship between wavelength and wave speed?

Back

Wave speed is equal to frequency multiplied by wavelength. If frequency increases, wavelength decreases, and vice versa.

Front

What is a wave?

Back

A wave is a disturbance that transfers energy from one place to another without transferring matter.

Front

What are the two main types of waves?

Back

The two main types of waves are mechanical waves (require a medium) and electromagnetic waves (do not require a medium).

Front

What is a crest in a wave?

Back

A crest is the highest point of a wave.

Front

What is a trough in a wave?

Back

A trough is the lowest point of a wave.

Front

What is frequency?

Back

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

Front

What happens to the energy of a wave as its wavelength increases?

Back

As the wavelength increases, the energy of the wave decreases.

What is the formula for wave speed?

Back

Wave speed = frequency × wavelength.
