refractive index of air, n1 = 1.0003
refractive index of water, n2 = 1.33
you will need the the angle of incidence, the angle at which the beam enters the water.
1) multiply n1 with the sine of the angle of incidence
2) divide the result in (1) by n2
3) then find the inverse sine of the result in (2)
