For the same angle of incidence, the angles of refraction in three different media A, B and Care `30^@ ,60^@ and 45^@ ` respectively. In which medium will the velocity or light be maximum?

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?

Write a relationship between angle of incidence and angle of refraction for a given pair of media.

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?

The velocities of light in two different media are 2* 10^8 m/s and 2.5 * 10^8 m/s respectively.The critical angle for these media is

A ray of light is incident on the surface of seperation of a medium at an angle 45^(@) and is refracted in the medium at an angle 30^(@) . What will be the velocity of light in the medium?

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.

If a ray of light in a denser medium strikes a rarer medium at an angle of incidence i, the angles of reflection and refraction are respectively, r and r' If the reflected and refraction rays are at right angles to each other, the critical angle for the given pair of media is

How are the angle of incidence and angle of refraction related to each other when : (a) a ray of light travels from rare to dense medium, (b) a ray of light travles from dense to rare medium ?

A ray of light is incident on a medium with angle of incidence I and refracted into a second medium with angle of refraction r. The graph of sin(i) vs sin(R) is as shown in figure. Then the velocity of light in the first medium in n times the velocity of light in the second medium. What shoul be th evalue of n?
