Show that the velocity of light in a rarer medium is greater than velocity in a denser medium.

According to Newton’s corpuscular theory, the velocity of light in rarer medium as compared to that in a denser medium is___________.

Write the ratio of velocity of light in first medium to the velocity of light in the second medium.

A light is travelling from air a medium the velocity of light in a medium is reduced to to 0.75 times the velocity n air assume that angle of incidence I is very small the deviation of the ray is

Explain how corpuscular theory predicts that the speed of light in a medium,say, water, is greater than the speed of light in vacuum.Is the prediction confirmed by experimental determination of the speed of light in water?

Answer the following questions If the refractive index of a rarer medium with respect to a denser medium is 0.5 what is the critical angle ?

Answer the following questions A ray of light is incident thobliquely at a boundary separating two media . What is its behaviour if the refractive index of the first medium is greater than that of the second medium ? Draw the corresponding neat and labelled diagrams.

Answer the following questions A ray of light is incident obliquely at a boundary separating two media . What is its behaviour if the refractive index of the second medium is greater than that of the first medium.

When light ray travels from denser medium to rarer, then it

The refractive index of a medium is 1.7 the velocity of light in this medium is

When sound is reflected from a denser medium,
