- The basic difference between types of radiation is their differing frequencies. Each frequency has an associated wavelength. As frequency increases across the spectrum, wavelength decreases. Energy also increases with frequency. Because of this, higher frequencies penetrate matter more readily.

The frequency of a light wave is how many waves move past a certain point during a set amount of time -- usually one second is used. Frequency is generally measured in Hertz, which are units of cycles per second.
As noted before, an electromagnetic wave has a frequency and a wavelength associated with it and travels at the speed of light, or c. The relationship among these wave characteristics can be described by vw = fλ, where vw is the propagation speed of the wave, f is the frequency, and λ is the wavelength.

The amount of energy in a light wave is proportionally related to its frequency: High frequency light has high energy; low frequency light has low energy. So, gamma rays have the most energy (part of what makes them so dangerous to humans), and radio waves have the least.
In general, the energy of a mechanical wave and the power are proportional to the amplitude squared and to the angular frequency squared (and therefore the frequency squared). Another important characteristic of waves is the intensity of the waves.
The relationship between wavelength and frequency is called an inverse relationship, because as the frequency increases, the wavelength decreases. Energy and amplitude Patterns 5 and 6 have the same wavelength and frequency but the amplitude is different.
