State two conditions necessary for total internal reflection to occur.
In the following figure, show two rays A and B travelling from water to air. If the critical angle for water- air surface is 48°, complete the ray diagram showing the refracted rays for each. State conditions when the ray will suffer total internal reflection.

How does a ray of light bend when it travels from when it is normal to the interface of the two media.
Why do diamonds sparkle?
If a ray of light passes from medium I to medium II without any change of direction, what can be said about the refractive indices of these media (angle I is not 0)?
How are critical angles related to the refractive index of the medium?
The diagram shows a point source P inside a water container. Three rays A, B, and C starting from P are shown up to the water surface. Show in the diagram the path of these rays after striking the water surface. The critical angle for the water-air pair is 48°.

Answer the following question.
Define the critical angle of incidence and obtain an expression for it.
Small air bubbles rising up a fish tank appear silvery when viewed from some particular angle is due to the ______.
