Example Input: Question: If Jim is projecting electromagnetic waves out into space and he increases the size of the wavelength being transmitted, what happens to the frequency of that wavelength? 
 Answer: decreases
Example Output:
Because all electromagnetic waves travel at the same speed through space, a wave with a shorter wavelength must have a higher frequency, and vice versa.
