Two transparent media A and B are separated by a plane boundary. The speed of light in those media are 1.5 x 10 8 m/s and 2.0 x 10 8 m/s, respectively. The critical angle for a ray of light for these two media is
Text Solution
Verified by ExpertsThe correct answer is:
Given that,
Speed of light in A, v A = 1.5 x 10 8 m/s
Speed of light in B, v B = 2 x 10 8 m/s
Now,
As we know for total internal reflection, ray of light should travel from denser to rarer medium
