365005 Assertion :
Higher is the refractive index of a medium or denser the medium, lesser is the velocity of light in that medium.
Reason :
Refractive index is inversely proportional to velocity.

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.

365006 Glass has refractive index \(\mu \) with respect to air and the critical angle for a ray of light going from glass to air is \(\theta \) . If a ray of light is incident from air on the glass with angle of incidence , corresponding angle of refraction is

1 \({\sin ^{ - 1}}\left( \mu \right)\)
2 \({\sin ^{ - 1}}\left( {\frac{1}{{{\mu ^2}}}} \right)\)
3 \({\sin ^{ - 1}}\left( {\frac{1}{{\sqrt \mu }}} \right)\)
4 \({\sin ^{ - 1}}\left( {\frac{1}{\mu }} \right)\)

365008 You are given four sources of light each one providing a light of a single colour-red, blue, green and yellow. Suppose the angle of refraction for a beam of yellow light corresponding to a particular angle of incidence at the interface of two media is \({\rm{90}}^\circ \). Which of the following statements is correct if the source of yellow light replaced with that of other lights without changing the angle of incidence?

1 The beam of red light would bend towards normal while it gets refracted through the second medium.
2 The beam of red light would undergo total internal reflection.
3 The beam of green light would bend away from the normal as it gets refracted through the second medium.
4 The beam of blue light would undergo total internal reflection.
