1) Suppose you are listening to a radio station at 91.5 MHz on the FM dial. The signals are coming to your radio using which main wavelength? Use c = 2.998 x 108 m/s

wavelength = _________ m

2)

Suppose you hit by a total of about 5,875. J of x-rays of frequency 2,509.0 petahertz. Use this: 1 petahertz = 1 x 10¹⁵ s^-1 or 1 x 10¹⁵ Hz.

About how many photos hit you?

Hint: first find the individual energy of each photon of the given frequency. Then divide the total energy by the individual energy.
