We cannot easily draw on this Wyzant platform. But here is a feeble attempt to show the relationship between wavelength and frequency.

In the first example, the wavelength is longer than it is in the 2nd example. The frequency, which is the number of wavelengths that pass a point in a given time, is shorter in the first example than in the 2nd example.
