Electromagnetic waves, which include light, consist of vibrations of electric and magnetic fields, and they all travel at the speed of light (3.00 x 108 m/s, or 300 million meters per second).

(a) Find the wavelength of an FM radio station signal broadcasting at a frequency of 104.5 MHz

(b) X rays have a wavelength of about 0.10 nm. What is their frequency?

(c) Microwave ovens cook food with electromagnetic waves of frequency around 2.45 GHz. What wavelength do these waves have? Please each part.
