Light having a wavelength in vacuum of 600 nm enters a liquid of refractive index 2.0.In this liquid,what is the wavelength of the light? (c = 3.0 × 10⁸ m/s) A)1200 nm B)600 nm C)300 nm D)150 nm E)200 nm

Question

Quizplus · Accepted Answer

The formula to find the wavelength of light in a medium is:

λm = λv/n

where λm is the wavelength in the medium, λv is the wavelength in vacuum, and n is the refractive index of the medium.

Substituting the given values, we get:

λm = 600 nm/2.0 = 300 nm

Therefore, the correct answer is C) 300 nm.
