Question

A light wave travels from air into a medium of refractive index 1.54. If the wavelength of the light in air is \(5.9\times10^{-7}\)m, calculate its wavelength in the medium

Options

A) \(2.5\times10^{-7}\)m

B) \(3.8\times10^{-7}\)m

C) \(4.6\times10^{-7}\)m

D) \(5.2\times10^{-7}\)m

E) \(6.1\times10^{-7}\)m

Explanation:

n =\(\frac{wavelength\, in\, air}{wavelength\, in \,medium}= \frac{5.9\times10^{-7}}{1.54}= 3.8\times10^{-7}\)m
