STATEMENT - 1
If the accelerating potential in an X - rays tube is increased, the wavelength of the characteristic X- rays do not change .
STATEMENT -2
When an electron beam strikes the target in an X- rays tube, part of the kinectic energy is converted into X - rays 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.
