The wavelength of the wave that you are tuning in decreases.
Step-by-step explanation:
The relation that relates with the speed of wave, frequency of wave and wavelength is given as
Wavelength =
The speed of the wave in a medium remains constant and therefore the wavelength is inversely proportional to the frequency of wave.
That is if the frequency is increased, the wavelength decreases and the wavelength is increased as the frequency is decreased.
Hence, as you tune your radio to a higher frequency, from 88.5 FM to 103,3 FM, the wavelength of the wave that you are tuning in decreases.
