Front

What type of waves have the longest wavelength?

Back

Radio waves have the longest wavelength in the electromagnetic spectrum.

Front

What type of waves have the shortest wavelength?

Back

Gamma rays have the shortest wavelength in the electromagnetic spectrum.

Front

What is the relationship between frequency and wavelength?

Back

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