An X - ray tube with a copper target emits `K_alpha` line of copper of wavelength 1.5 Å. What should be the minimum voltage through which the electrons should be accelerated to produce this wavelength of X rays ?

A

8280 V

B

828 V

C

82800 V

D

8.28 V

Text Solution

Verified by Experts

The correct Answer is:
A
`eV=(hc)/lamdaimpliesV=(6.6 xx10^(-34)xx3xx10^8)/(1.6 xx10^(-19)xx1.5 xx10^(-10))~~8250` Volt
This value is nearby to 8280 Volt
