Remember that the relationship between wavelength and Frequency is
defined by the equation ---

c = Lambda X Nu

where
c = 300,000,000 meters per second
Lambda = wavelength (in meters)
Nu = Frequency in cycles per second

Thus solving for either lambda or nu reveals an inversely proportional
relationship between the two.

Consequently as the number of cycles per second (frequency) increases,
the wavelength shortens.
