The speed of light in media `M_(1)` and `M_(2)` is `1.5xx10^(8)` m/s and `2.0xx10^(8)` m/s respectively. A ray of light enters from medium `M_(1)` to `M_(2)` at an incidence angle i. If the ray suffers total internalreflection the value of i is -

B. Equal to or less than `sin^(-1)(3/5)`
C. Equal to or greater than `sin^(-1)(3/4)`
D. Less than `sin^(-1)(2/3)`

Answer
