A monochromatic light source emits a wavelength of 403 nm in air.When passing through a liquid,the wavelength reduces to 363 nm.What is the liquid's index of refraction?
A)1.23
B)1.05
C)1.11
D)1.90
E)1.81

We can use the equation n2/n1 = λ1/λ2, where n1 is the index of refraction in air (which is approximately 1), n2 is the index of refraction in the liquid, λ1 is the original wavelength, and λ2 is the new wavelength. Plugging in the values given, we get n2/1 = 403/363, which simplifies to n2 = 1.11. Therefore, the liquid's index of refraction is 1.11. Choice C is the correct answer.
