What is the relationship between the frequency and the wavelength of electromagnetic energy?

Generally speaking, the frequency of a wave varies inversely with the wavelength. So if the wave has a high frequency it will have a short wavelength (the distance from crest to crest or trough to trough). Similarly, if the wave has a low frequency it will have a long wavelength. The frequency indicates how many waves pas a given point per second, so the longer the wavelength, the less waves pas in a second, giving the wave a low frequency. Frequency and wavelength can also be used to calculate the speed of light (2.998 x 10^8 m/s) by multiplying them together.
