Question

Which of the following describes the relationship between frequency and wavelength?

As frequency increases, wavelength increases.

As frequency decreases, wavelength decreases.

As frequency increases, wavelength decreases.

As frequency increases, wavelength is unaffected.

Answer 1

As frequency increases, wavelength decreases.

velocity=frequency * wavelength
so frequency is inversely proportional to wavelength.

Answer 2

This might help: http://img.tfd.com/cde/WAVELEN.GIF It shows wavelength, frequency and amplitude on a graph.

If you have 5 oscillations in one second, and those oscillations have a certain wavelength, how would that wavelength change if you had to fit 10 oscillations into one second? Just look at the graph: if you're trying to put more oscillations into a shorter amount of time, the waves need to be shorter so you can fit them all in.
