Shortest wavelength limit of X-rays produced by an X-ray tube to be operating at 30 kV is `0.414Å`. Planck's constant is:

A

`5.623xx10^(-34)J-sec`

B

`5.89xx10^(-34)J-sec`

C

`6.52xx10^(-34)J-sec`

D

`6.624xx10^(-34)J-sec`

Text Solution

Verified by Experts

The correct Answer is:
D
`hv=(hc)/(lambda)=eV`
`:.v=(eV lambda)/(c)=6*624xx10^(-34)J` sec.
