Assertion : The colour of light emitted ...

Assertion : The colour of light emitted by a LED depends on its forward biasing.
Reason : The reverse biasing of p-n junction will lower the width of depletion layer.

A

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

B

if both the Assertion and Reason are true but the reason in not a correct explanation of the Assertion.

C

if the Assertion is true but the Reason is false.

D

if both Assertion and Reason are false.

Text Solution

Verified by Experts

The correct Answer is:
D
The colour of light emitted by LED depends upon the nature of semiconductor material used in making the KED. Hence Assertion is wrong. Here, the reason is also wrong.
