The velocity of a certain monochromatic light, in a given transparent medium is `2.25xx 10^(8)m//s`. What is the (a) critical angle of incidence, (b) polarising angle for this medium?

Explanation

To solve the problem, we need to find the critical angle of incidence and the polarizing angle for a given medium where the velocity of light is \(2.25 \times 10^8 \, \text{m/s}\).
