Example Question #332 : Ap Physics 2

A beam of light is traveling at approximately  in a very dense medium. Given that the frequency of the light beam is , what is the wavelength of the light beam? Suppose that the speed of light in a vacuum is 

Possible Answers:

Correct answer:

Explanation:

The wavelength of the light beam doesn't depend on the speed through the medium. As such, as can solve for wavelength  by simply solving:

Where  is frequency and  is the speed of light in a vacuum.
