Question

if the angle of refraction is 30 and relative refractive index is 1 then calculate angle of emergence

Answer 1

Answer:

Explanation:

by Snell's law ,

sin(i)/sin(r) = constant

as sin(r)=sin (30) = 1/2

sin(i)/sin(30)=1

sin(i)=sin(30)

therefore , sin(i)= 1/2 or i=30

also i= angle of emergence ,

so angle of emergence is 30 degree hope it helps!
