A ray of light is incident at an angle of incidence, i, on one face of prism of angle A (assumed to be small) and emerges normally from the opposite face. If the refractive index of the prism is μ, the angle of incidence i, is nearly equal to: [2012]
  • a)
    μA
  • b)
    μA/2
  • c)
    A/μ
  • d)
    A/2μ
Correct answer is option 'A'. Can you explain this answer?

For normally emerge e = 0
Therefore r2 = 0 and r1 = A
Snell’s Law for Incident ray’s
1 sin i = μ sin r1 = μsin A
For small angle
