If light from a 560 nm monochromatic source in air is incident upon the surface of fused quartz (n = 1.56)at an angle of 70°,what is the wavelength of the ray refracted within the quartz?
A) 560 nm
B) 874 nm
C) 192 nm
D) 359 nm

Question

Quizplus · Accepted Answer

The wavelength of light in a medium is given by λ_medium = λ_air / n. Here, λ_air = 560 nm and n = 1.56. So, λ_quartz = 560 nm / 1.56 ≈ 359 nm.
