Use Snell’s law to calculate the angle of emergence (deflection angle) from the medium into air based on the angle of incidence.
| Declination (θ2) | degrees Angle of emission into the atmosphere (total deviation angle) |
| Declination (θ3) | degrees Angle of emission into the atmosphere (deviation angle) |
Snell’s Law: n2*(sinθ2) = n1*(sinθ1): n2 => refractive index of air (=1); n1 => refractive index of the medium
Formula: θ2 = sin^-1(n1*(sinθ1))
θ3 = θ2 - θ1
I have also posted a formula that applies this equation to calculate the angle of emergence for a right-angled prism (not a right-angled isosceles triangle).
Please use it in conjunction with this one.
