Question

Rays of light fall on a glass slab $(\mu >1)$ as shown in figure. If $\mu$ at A is maximum and at B it is minimum, then what will happen to these rays?

• A. They will tilt towards A
• B. They will tilt towards A
• C. They will not deviate
• D. There will be total internal reflection

Answer 1

The correct option is C They will not deviate

For normal incidence, whatever be refractive index.
i = 0, r = 0. So there is no deviation of ray.
