Manipal MET2018PhysicsRay Optics
The light ray is incident at angle of 60^ on a prism of angle 45^ . When the light rays falls on the other surface at 90^ , the refractive index of the material of prism and the angle of deviation are given by
Options
- A= 2 , =30^
- B=1.5, =15^
- C= 3 2 , =30^
- D= 3 2 , =15^
Correct answer
D. = 3 2 , =15^
Step-by-step solution
From the problem it is clear that e= r₂=0 From A=r₁+r₂ array lc & r₁=A=45^ & = i r₁ = 60^ 45^ = 3 2 array Also, from i+e=A+ array ccc & 60+0 & =45+ & & =15^ array
