A monochromatic light source emits a wavelength of 490 nm in air.When passing through a liquid,the wavelength reduces to 389 nm.What is the liquid's index of refraction?
A) 1.26
B) 1.33
C) 1.14
D) 1.49

Question

Quizplus · Accepted Answer

The index of refraction (n) is calculated using the formula n = λ_air / λ_liquid. Substituting the given values, n = 490 nm / 389 nm = 1.26.
