A monochromatic beam of light in air has a wavelength of 589 nm in air.It passes through glass (n = 1.52)and then through carbon disulfide (n = 1.63).What is its wavelength in the carbon disulfide?
A)361 nm
B)387.5 nm
C)895 nm
D)960 nm

Question

Quizplus · Accepted Answer

The wavelength of light in a medium is given by λ_medium = λ_air / n_medium. For carbon disulfide, λ = 589 nm / 1.63 = 361 nm.
