The angle of incidence is
The refractive index of water is
Generally Snell's law is mathematically represented as
Here is the refractive index of air with value
is the angle of refraction
So
=>
=>
Given that the angle should not be greater than then the angle of incidence will be
=>
=>
Generally for critical angle is mathematically represented as
