A ray of light travelling in a transparent medium of refractie index mu falls on a surface separatign the medium from air at an angle of incidence of 45^@ .For which of the following velues of mu ,the ray can indergo total internal reflection?

What is the unit of refractive index?

Light enters at an angle of incidence in a transparent rod of material of refractive index mu . The light once entered into it will not leave it through its lateral face, whatsoever be the value of angle of incidence, if

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?

A light of wavelength 6,000 overset @A in air, enters a medium with refractive index 1.5.What will be frequency and wavelength of light in the medium?

A ray of light falls on a transparent glass slab of refracative index 1.62. If the reflected ray and refracted rays are mutually perpendicular. What is the angle of incidence? Give calculations.
