On operating an X-ray tube at 1 kV. X-rays of minimum wavelength `6.22Å` are produced. If the tube is operated at `10 kV`, then the minimum wavelength of `X`-rays produced will be

A

`0.622Å`

B

`6.22Å`

C

`3.11 Å`

D

`62.2 Å`

Text Solution

Verified by Experts

The correct Answer is:
A
`lambda_(mn)prop (1)/(V) so (lambda)/(6.22) = (1)/(10) rArr lambda_(min)=0.622 A`
