Refraction Through a Prism
Prism - A prism is a transperent medium enclosed by two plain refracting surfaces.
In the given figure :-
A - Angle of Prism
1st Medium = Air
2nd Medium = Glass
μ - Refractive index of glass.
PQ is Incident Ray
RS is Emergent Ray
n1 and n2 are the normals meeting at O.
δm = Angle of minimum deviation
μ = sin [(A + δm)/2] / sin A/2
