MHT CET Physics question
The refractive index of water is 4/3 and that of glass slab is 5/3. The critical angle for the ray of light tending to go from glass to water is
Answer: (A)
Solution
sin C = μ_w/μ_g = 4/5; (b) and (d) have sine greater than 1 and (c) is not 4/5. Hence the correct option is (a).
