If the speed of light in medium 1 is more than in medium 2, then medium 1 is called optically…………and medium 2 is called optically…………… .

Calculate the speed of light in a medium whose critical angle is 180^@ .

What is the speed of light in a dense medium of polarising angle 30^@ ?

Why ether was called a hypothetical medium?

What is the effect when light enters from a rarer medium to a denser medium? Explain with diagram

What happens to the wavelength of light when it goes from rarer to denser medium?

Why is SO_2 a better reducing agent in alkaline medium than in acidic medium ?

Explain how Corpuscular theory predicts the speed of light in a medium, say, water, to be greater than the speed of light in vacuum. Is the prediction confirmed by experimental determination of the speed of light in water ? If not, which alternative picture of light is consistent with experiment?
