Question

45
The above figure shows a ray of light meeting the surface of
rectangular glass slab at an angle of incidence 450. Assuming that
the RI of the material of glass slab is v2, Find the angle of
refraction.
ing the nath of ray of light through the​

Answer 1

SOLUTION-;

• When light falls perpendicularly or normally on the surface of a glass slab, it goes straight. There is no bending of ray of light on entering the glass slab or coming out of it. In this case angle of incidence and angle of refraction is zero
