Front

What is the electromagnetic spectrum?

Back

The range of all types of EM radiation, ordered by frequency or wavelength.

Front

What is the relationship between frequency and wavelength in electromagnetic waves?

Back

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