Assertion : Diamond are known for their spectacular brilliance, but diamonds found in nature rarely exhibit the brilliance.
Reason : By cutting the diamond suitably, multiple total internal reflections can be made to occur.

A

If both assertion and reason are true and reason is the correct explanation of assertion.

B

If both assertion and reason are true and reason is not the correct explanation of assertion.

C

If assertion is true but reason is false.

D

If both assertion and reason are false.

Text Solution

Verified by Experts

The correct Answer is:
A
The critical angle for diamond-air interface is very small, therefore once light enters a diamond, it is very likely to undergo total internal reflection inside it. It is the technical skill of a diamond cutter which makes diamond to sparkle so brilliantly.

Assertion (A) : Diamond does bnot reflect light . Reason (R) : Diamond has low refractive index.

Assertion: In ionospheric reflection, phase change does not occurs with the light wave. Reason: The ionosphere reflection is similar to the tatol internal reflection is similar to the total internal reflection in miral.

Sparking Brilliance of Diamond: The total internal reflection of the light is used in polishing diamonds to create a sparking brilliance. By polishing the diamond with specific cuts, it is adjusted the most of the light rays approaching the surface are incident with an angle of incidence more than critical angle. Hence, they suffer multiple reflections and ultimately come out of diamond from the top. This gives the diamond a sparking brilliance. Light cannot easily escape a diamond without multiple internal reflections. This is because:
