A glass prism `(mu = 1.5)` is dipped in water `(mu = 4//3)` as shown in figure. A light ray is incident normally on the surface AB . It reaches the surface BC after totally reflected, if

`sin theta ge 8//9`

`2//3 lt sin theta lt 8//9`

`sin theta le 2//3`

It is not possible

Figure shows a glass (mu_(g) = 1.5) vessel, partly filled with water ( mu_(w) = (4)/(3)) . A ray of light is incident normally on the water surface and passes straight through. The vessel is tilted slowly till angle theta such that the light ray is emergent grazing the lower surface of the glass. Find theta .
