Answer 2

Answer:

A ray of light falls normally on the surface of a transparent glass slab. Draw a ray diagram to show its path and also mark angle of incidence and angle of emergence.

Explanation:

• When a ray of light normally on the surface of a transparent glass slab then the angle of incidence and angle of reflection-
• If the ray of light falls normally on the surface of transparent glass slab, I that is angle of incidence is equal to zero that is I=0
• Then r that is angle of reflection is also equal to zero that is r=0
• Therefore u is equal to the ratio of Sin of angle of incidence and sin of angle of reflection. That is-
• $u= \frac{sin i}{sin r}$
• Therefore angle of emergence is also equal to zero.
• That is angle of emergence =0

Hence, When a ray of light normally on the surface of a transparent glass slab then the angle of incidence and angle of reflection is zero.
