Chapter 26, Problem 126CCP

Concepts: (i)

To determine

The factors on which critical angle depend on glass-water interface.

(ii)

To determine

The angle of refraction and to relate angle ${\theta }_1$ with the critical angle.

(iii)

To determine

The relation between angle of refraction ${\theta }_3$ and angle of incidence ${\theta }_2$ in glass-liquid interface.

(iv)

To determine

To check: Whether the ray passing from the liquid into the air is refracted or reflected.

Calculation:

To determine

The angle of refraction ${\theta }_5$.
