The photoelectric work function of potas...

The photoelectric work function of potassium is 2.3 eV. If light having wavelength of 2800 `A^@` falls on potassium , find
the stopping potentail in volts.

Text Solution

Verified by Experts

`K _(max) = e V_0, therefore 2.1 e V = e V_0`
or `V_0 = 2.1 V`.
