364992 A light ray falls on a glass surface of refractive index \(\sqrt 3 \) , at an angle 60°. The angle between the refracted and reflected rays would be

1 60°
2 90°
3 120°
4 30°

364993 Assertion :
There is no dispersion of light refracted through a rectangular glass slab.
Reason :
Light is completely absorbed by glass slab.

1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but reason is correct.

364994 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 is \(n\) times the velocity of light in the second medium. What should be the value of \(n\)?
