When light travels from optically denser medium to optically rarer medium it bends towards the normal.

When a beam of light passes form optically rarer medium to optically denser medium,it bends…….the normal.

Derive the relation:- frac(mu_2)(v) - frac(mu_1)(u) = frac(mu_2 - mu_1) (R) when light undergoes refraction fromoptically rarer to optically denser medium at curved surface.

For a ray of light travelling from a denser medium of refractive index mu_1 to a rarer medium of refractive index mu_2 ,prove that (mu_2)/(mu_1) = sin C , where C is the critical angle of incidence for the media.

When light passes from one medium to another medium, which one of these quantities, remains unchanged.

A plane wave front AB propagating from denser medium (1)into a rarer medium (2) is incident on the surface P_1P_2 separating the two media as shown in the figure. Using Huygen's principle, draw the secondary wavelets and obtain the refracted wave front in the diagram.

When light travels from air to water, which parameter does not change?

Light from a denser medium I goes to a rarer medium II.When angle of incidence is theta ,the reflected and refraced ray s are perpenciculat to each other .The crtitical angle is:
