Describe the relationship between the frequency, wavelength, and velocity (speed) of a wave. - AnswerThe 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 Calculate any one (frequency, wavelength, or velocity) given the...
