Question:

In one portion of a synchrotron, electrons traveling at 2.99 × 108 m/s enter a region of uniform magnetic field with a strength of 0.599 T.
(a) What is the acceleration of an electron in this region? (Ignore the effects of relativity.)
(b) The largest amount of light is emitted by the synchrotron at a frequency given by f = (0.0433) a Hz, where a is the acceleration in m/s2. What are this frequency and its corresponding wavelength? In what portion of the electromagnetic spectrum do these waves belong?
