Assertion: If applied potential difference in coolidge tube is increased, then difference in coolidge tube.

A

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

B

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

C

If Assertion is true, but the Reason is false.

D

If Assertion is false but the Reason is true.

Text Solution

Verified by Experts

The correct Answer is:
B
`Delta lambda = lambda_(Ka) - lambda_(min)`
Here, `lambda_(min) (in Å) = (12375)/(V(in volta))`
If V is increased, `lambda_(min) decreases. Therefore, `Deltalambda` increases.
