The dependence of the short wavelength limit `lamda_(min)` on the accelerating potential `V` is represented by the curve of figure

A

A

B

B

C

C

D

None of these

Text Solution

Verified by Experts

The correct Answer is:
A
`lamda_("min") =(hc)/(eV_0)implies log(lamda_("min"))=log""(hc)/e-logV`
[Graph having ve - slope and intercept `(log""(hc)/e)` is A]
