Question

A ray incident at an angle 53 on a prism emerges at an angle 37

Answer 1

Answer:

let "n" be refractive index of prism. And we take n=1 because , n is always use in both cases. Use Snell`s law, thenSin53=nsinr1 Or r2=n53=53Again Use Snell`s law,nsinr2=sin37 or r2=37n=37We know that , r1+r2=A or 53+37=A=90Now, When i=50 then , Use Snell`s lawSin50=nsinr1 or r1=n50=50 And r1+r2=A 50+r2=90 or r2 = 40, NOW AGAIN Use Snell`s law, nsin40=sine or e= 40
