A ray of light in air with a wavelength of 600 nm is incident on a liquid with an index of refraction of 1.5.The ray of light makes an angle of 45 degrees with the normal when it enters the liquid.What is the wavelength of the ray of light in the liquid?

Question

Quizplus · Accepted Answer

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

λ(medium) = λ(air) / n(medium)

where λ is the wavelength and n is the index of refraction.

Substituting the values given in the question:

λ(liquid) = 600 nm / 1.5 = 400 nm

Therefore, the wavelength of the ray of light in the liquid is 400 nm, which is option B.
