A ray travelling from glass to air, bends away from the normal. ____

A ray of light travelling obliquely from glass to air :

When a ray of light travels obliquely from a rarer medium to a denser medium, it bends away from the normal.

(a) State Snell's law of refraction of light. (b) A transparent medium A floats on another transparent medium B. When a ray of light travels obliquely from A into B, the refracted ray bends away from from the normal. Which of these two media A or B are optically denser and why ?

A : When a diver under water looks obliquely at a fisherman standing on the bank of a lake then fisherman looks taller. R : When a ray of light travelling in air enters water, it bends towards the normal.

In the figure, you can see a light ray travelling from air to glass. Why is there no refraction?

A converging set of ray, traveling from water to air, is incident on a plane interface. In the absence of the interface, the rays would have converged to a point O, 60 cm above the interface. However, dur to refraction the rays will bend. At what distance above the interface will the rays actually converge?

Is the formula "Real depth/Apparent depth = mu." valid if viewed from a position quite away from the normal ?

A ray of light travelling in air enters obliquely into water. Does the light ray bend towards the normal or away from the normal ? Why ?

A light ray is travelling from air to glass. True reflected and refracted rays are perpendicular to each other. If the angle of incidence in air is I the refractive index of glass is

Figure alongside shows 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 for each. State conditions when the ray will suffer total internal reflection.
