Describe the relationship between the frequency, wavelength, and velocity (speed) of a wave. 
The more times the wave is passing through a point in space = a higher frequency, the higher 
frequency creates a smaller wavelength, which is why the smallest wave is a gamma wave, it has 
the highest frequency and the shortest distance between waves, the velocity can be measured in 
m/s and is composed of frequency and wavelength
