6(a)
A diver in water looks obliquely at an object AB in air.
Show the path of two rays AC and AD starting from the tip of the object as it travels towards the diver in water and hence obtain the image of the object.

From the figure given below, the refractive index of medium B with respect to medium A (ₐμᵦ) is:
(a) sin 45° / sin 30°
(b) sin 30° / sin 45°
(c) sin 45° / sin 60°
