In producing X-rays a beam of electrons accelerated by a potential difference V is made to strike a metal target. For what value of `V,X`-rays will have the lowest wavelength of 0.3094 Å

A

10 kV

B

20 kV

C

30 kV

D

40 kV

Text Solution

Verified by Experts

The correct Answer is:
D
`V=(12375)/(lamda_("min"))=(12375)/(0.3094)~~40kV`
