Q)
(chatquestion)...A transparent solid cylindrical rod has a
refractive index of 2/V3. It is surrounded
by air. A light ray is incident at the
midpoint of one end of the rod as shown
in the figure.
The incident angle 0 for which the light ray
grazes along the wall of the rod is :
1
sin-1 (1/2)
2
sin-1 (v2/2)
3
sin-1 (2/v3)
4
sin-1 (1/v3)
...
