Assertion : Now a days a standard metre is defined as in terms of the wavelength of light.
Reason : Light has no relation with length.

A

If both assertion and reason are true and the reason is the 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 assertion is true but reason is false.

D

If the assertion and reason both are false

Text Solution

Verified by Experts
