Show full solutionCorrect option: B
Correct answer
BThe spectrum of visible light whose frequency is less than that of green light will come out to the air medium

Step-by-step explanation

sin θ c = 1 μ

For greater wavelength (i.e lesser frequency) μ is less So, θ c would be more. So, they will not suffer reflection and come out at angles less than 90 ∘ .
