When light goes from an optically rarer to an optically denser medium,
  • a)
    angle of incidence < angle of refraction
  • b)
    angle of incidence = angle of refraction
  • c)
    angle of incidence > angle of reflection
  • d)
    angle of incidence > angle of refraction
Correct answer is option 'D'. Can you explain this answer?
Verified Answer
When light goes from an optically rarer to an optically denser medium,...
Critical angle is related to the refractive index of the medium as:
μ = 1 / sinC
Different colours have different wavelength and hence the refractive index is different for different colours.
Therefore critical angle depends on the colour of the light.
