(Answered) In vacuum the wavelength of the light in your laser pointer

Academics

In vacuum, the wavelength of the light in your laser pointer is 538 nm. Standing at the shore of a calm pond, you shine the laser beam onto the water surface at an angle of 60 ° from the normal to the surface. The index of refraction for the water is n = 1.333.

Part A

What is the wavelength of the light as it enters the water?

λ =

Part B

What is the frequency of the light as it enters the water

f =

Part C
