The speed of light decreases as it passes from an optically denser medium to an optically rarer medium.

What is optically denser and optically rarer medium ?

What is the effect on the speed and wavelength of light when the light wave refracted from denser medium to rarer medium ?

Light waves travel from optically rarer medium to optically denser medium. Its velocity decreases because of change in .......

According to particle theory of light what is the velocity of light in a dense medium, compared to that in rare medium ?

A ray of light enters in denser medium from rarer medium. Speed of light in rarer medium is double than that in denser medium, what is the critical angle for total internal reflection ?

Explain rarer and denser medium.

Light ray bends when it travels from one medium to another medium because ......

A ray of light is travelling from a denser medium to rarer medium. For these media the critical angle is C. The maximum possible deviation of the ray is ........... [Hint : The situation at total reflection is shown in the figure.]

The medium in which the speed of light is half of the speed in air, if light travels from such medium to air, then for what angle of incidence light will do total internal refelction ?

Assertion : Newton's rings are formed in the reflected system. When the space between the lens and the glass plate is filled with a liquid of refractive index greater than that of glass, the central spot of the pattern is bright. Reason : This is because the reflections in these cases will be from a denser to a rarer medium and the two interfering rays are reflected under similar conditions.
