Assertion:Minimum deviation by an equila...

Assertion:Minimum deviation by an equilateral prism of refractive index sqrt2 is `30^@.`
Reason: It is from the relation, `mu=sin((A+delta_m)/2)/sin(A/2)`

A

If both Assertion and Reason are true and the Reason is correct explanation of the Assertion.

B

If both Assertion and Reason are true but Reason is not the correct explanation of the Assertion.

C

If both Assertion is true, but the Reason is false.

D

If both Assertion is false but the Reason is true.

Text Solution

Verified by Experts

The correct Answer is:
A
`A=60^@ and delta_m=30^@`
Substituting the values, we get
`mu=sqrt2`
