The frequency v of incident radiation is...

The frequency v of incident radiation is greater than threshold frequency `( v_(0))` in a photocell. How will the stopping potential vary if freqquency `( v)` is increased, keeping other factors constant ?

Text Solution

Verified by Experts

From Einstein's photoelectric equation, stopping potential `V_(0)` is
`eV_(0) = hv - hv_(0) . V_(0) = ( h )/( e ) ( v -v_(0))`
Given `v gt v_(0)`, so with increase of frequency v, stopping potential increases.
