When a ray of light travelling in glass enters into water obliquely:

When a light ray travels obliquely from glass to air, it bends towarrds the normal.

Answer the following questions : (a) You have learnt that plane and convex mirrors produce virtual images of objects. Can they produce real images under some circumstances ? Explain. (b) A virtual image, we always say, cannot be caught on a screen. Yet when we see a virtual image, we bring it to screen i.e. retine of our eye. Is there a contradiction ? ( c) A diver under water looks obliquely at a fisherman standing on the bank of a lake. Would the fisherman look taller or shorter than what he actually is ? (d) Does the apparent depth of a tank of water change if viewed obliquely ? If so, does the apparent depth increase or decrease ? ( e) The refractive index of diamond is much greater than that of ordinary glass. Is this fact of some use to a diamond cutter ?

When a rays of light enters a glass slab from water

When light comes from air to glass, the refracted ray is bent towards the normal. Why ?
