Chem 141 exam 2 MSU Questions and Answers 100% Pass 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 Calculate a...
