In this problem, we have been given that there is an incident ray and this incident ray falls onto a bubble.
00:08
And we have to figure out that this incident ray after passing through this water bubble, that goes through which path here, whether it goes from a, b, c, d, or e.
00:21
So as we know that the incidentary is passing from air and it goes on to the water surface.
00:28
So here, water is comparatively optically more denser as compared to air.
00:33
So in that case, if we just construct a normal over here, the incident ray after refraction that's going to pass such that it bends towards the normal.
00:44
So, of course, the bending will be somehow so that it appears to be like it has bent towards the normal.
00:53
And here, the ray has to emerge out of this surface now...
