Light travels more quickly through water than through glass. (a) Which is optically denser : water or glass ? (b) If a ray of light passes from glass into water, which way will it bend : towards the normal or away from the normal ?

Q. A light ray passes through a glass slab at an angle from air. The same glass slab is now placed in a tank of water. If the same light ray is now allowed to pass through the glass slab, compare the lateral displacement of the light ray in both the cases.
(Given that

n_{w a t e r} = 1.33

and

n_{g l a s s} = 1.5

Light is incident from air on oil at an angle of $30^{\circ}$ . After moving through oil-1 and another medium; oil-2, it enters glass and then it enters the water. If the refractive indices of glass and water are $1.5$ and $1.3$ , respectively, find the angle which the ray makes with normal in water.

Q. Find the lateral shift of light ray while it passes through a parallel glass slab of thickness

10 cm

placed in air. The angle of incidence in air is

60^{\circ}

and angle of refraction in glass is

45^{\circ}

Q. Trace the path of the ray of light through a glass slab, when it passes from water to a glass slab and what will happen to the incident ray ? Draw the ray diagram.
