Assertion -The refractive index of diamond is sqrt 6 an that of a liquid is sqrt 3- If light travels from diamond to the liquid- it will be totally reflected when the angle of incidence is displaystyle 30-circ- Reason- displaystyle mu -frac-1-sin c- where mu is the refractive index of diamond w-r-t liquidBoth Assertion and Reason are correct and Reason is the correct explanation AssertionBoth Assertion and Reason are correct but Reason is not the correct explanation AssertionAssertion is correct but Reason is incorrectAssertion is incorrect but Reason are correct

-x221A-6Sin-x3B8-x221A-3Sin90-x27F6-x3B8-45oSo the angle of incidence has to be more than 45-x2218- for total internal reflectionThe assertion is wrong- The reason is correct

√6Sinθ=√3Sin90⟶θ=45oSo the angle of incidence has to be more than 45∘ for total internal reflectionThe assertion is wrong. The reason is correct

$\sqrt{6} S i n θ = \sqrt{3} S i n 90$

$⟶ θ = 45^{o}$

So the angle of incidence has to be more than $45^{\circ}$ for total internal reflection
The assertion is wrong. The reason is correct
