Radiation produced by accelerating charges

[Plmzaq]

Hey, I am doing a question for a physics assignment, and it asks me to find the "wavelength of radiation produced by a proton in a cyclotron with a radius of 0.500 m and magnetic field with a magnitude of 0.200 T." Unfortunately the textbook doesn't give me an equations that have anything to do with frequency or wavelength of radiation from accelerating particles. Any help would be just wonderful.

1. Find the required velocity of the proton by equating magnetic and centripetal forces.

2. Given velocity and radius find the period (T) of each rotation.

3. Use f = 1/T and centripetal = c/f
