D)300 nm
E)900 nm

Question

Quizplus · Accepted Answer

The relationship between the wavelength of light in vacuum and the wavelength of light in a medium is given by:

n = λ_vacuum / λ_medium

where n is the refractive index of the medium, λ_vacuum is the wavelength of light in vacuum and λ_medium is the wavelength of light in the medium.

Rearranging the equation to solve for λ_medium, we get:

λ_medium = λ_vacuum / n

Substituting the values given, we get:

λ_medium = 600 nm / 1.5 = 400 nm

Therefore, the wavelength of the light in the glass is 400 nm.
