In each of the questions, assertion(A) is given by corresponding statement of reason (R) of the statemens. Mark the correct answer.
Q. Statement I: If the accelerating potential in an X-ray tube is increased, the wavelentghs of the characteristic X-rays do not energy.
Statement II: When an electron beam strikes the target in an X-ray tube, part of the kinetic energy is converted into X-ray energy.

A

If both Statement I and Statement II are true , Statement II is correct explaination of the Statement I.

B

If both Statement I and Statement II are true , Statement II is not the correct explaination of the Statement I.

C

If Statement I is true , statement II is false.

D

If Statement I is false , statement II is true.

Text Solution

Verified by Experts

Cut-off wavelength depends on the applied voltage and not on the Characteristic wavelength .Further , approxi-matelly `2%` kinetic energy of the electron is utilized in producuing X-rays . Rest `98%` is lost in neat.
Therefore option (b) is correct.
