Answer to Question #161140 in Physics for Hafiz

Question

A thin film of water on glass has an index of refraction of 1.33. Red light of wavelength 600 nm strikes the surface of the water. What is the wavelength of the light that refracts into the water? (Pick the best answer) a. Depends on the thickness of the water. b. Depends on the index of refraction of the glass. c. 430 nm d. 221 nm

Answer 1

The best answer is 430 nm because the wavelength refracted in the water shrinks to 600/1.33=450 nm.
