A beam of monochromatic electromagnetic radiation in air has a measured wavelength of 520nm. Assume the speed of light in vacuum is 3.00×108m/s, the same as in air for the purpose of this problem.
(a) Calculate the frequency of the radiation, expressing your answer in hertz with an appropriate number of significant figures.
(b) Identify the region of the electromagnetic spectrum to which this radiation belongs. Support your answer with numerical reasoning based on typical wavelength ranges.
(c) State the perceived color of this radiation to the human eye and briefly explain how your answer in part (b) leads to this conclusion.
