Question

Q.(A)Student by performing experiment of reaction of light in the library knows down different observation refer to the same and briefly explain the Conclusion and the reason when the rays fall the glass blocked perpendicularly there is no bending of light.
(B) find out the index of refraction in a medium where the speed of light 1.5X10^8 m/s.​

Answer 1

Answer:

. We know that angle of incidence is equal to angle of emergence.

And for a light ray going from rarer to denser medium we also know that angle of incidence is greater than angle of refraction

Thus it implies that angle of emergence is greater than angle of refraction.

C. Since angle of emergence is equal to angle of incidence, thus emergent ray is parallel to incident ray.
