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?

Write the ratio of velocity of light in first medium to the velocity of light in the second medium.

Write the ratio of velocity of light in first medium to the velocity of light in the second medium.

When light is incident on a medium at angle i and refracted into a second medium at an angle r, the graph of sin i vs sin r is as shown in the graph, From this, one can conclude that

When light is incident on a medium at angle i and refracted into a second medium at an angle r, the graph of sin r versus sin i is as shown. From this one can conclude that (i) the velocity of light in second medium is sqrt3 times the velocity of light in the first medium (ii) the velocity of light in the first medium is sqrt3 times the velocity of ligth in second medium (iii) the critical angle of the two media is given by sin i_C=1sqrt3 (iv) the critical anlge of the two media is given by sin i_C=1sqrt2

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