For the production of X rays of wavelength 0.1 Å the minimum potential difference will be

A

248 KV

B

124 KV

C

12.4 KV

D

24.8 KV

Text Solution

Verified by Experts

The correct Answer is:
B
`lamda_("min") = (12400)/(V) Å`
`therefore V = (12400)/(lamda) = (12400)/(0.1) = 124xx10^3 V = 124 KV`
