The speed of light in media `M_1` and `M_2` are `1.5 xx 10^8 m//s and 2.0 xx 10^8 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 internal reflection, the value of `i` is.

Options

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

Answer

B
