In the diagrams given in Figure C, draw the angle of incidence and the angle of refraction. Identify which medium is rarer and which medium is denser.

Observe the given figure and identify which medium is optically denser and which is optically rarer.

(I) How does the refractive index of a medium depends on the wavelength of light used? (II)Which is greater, angle of incidence or angle of refraction, when light travels from denser medium to rarer medium.

A ray of light passes from vaccum into a medium of refractive index n. If the angle of incidence is twice the angle of refraction, then the angle of incidence is

Explain refraction. Draw a diagram and explain incident ray, refracted ray, angle of incidence, and angle of refraction.

Looking at the angle of refraction in the figures given Fig. B, which medium will have the maximum value of refractive index and in which medium will the speed of light be the least?

Draw a diagram to show refraction through a glass slab and label the following: (a) incident ray (b) refracted ray (c) emergent ray (d) angle of incidence (e) angle of refraction at the first boundary of two mediums (f) angle of emergence and (g) lateral displacement

For the same angle of incidence, the angles of refraction in three different media A, B and C are 15^(@), 25^(@) and 35^(@) respectively. In which medium, will the velocity of light be minimum ?

For the same angle of incidence in media P,Q and R, the angles of refraction are 35^@, 25^@,15^@ respectively. In which medium will the velocity of light be minimum?

Consider a ray of light passing from one medium to another. If the angle of refraction is less than the angle of incidence, will the speed of light in the second medium be less or more than that in the first medium?

For total internal reflection to take place, the angle of incidence i and the refractive index mu of the medium must satisfy the inequality
