Differing stopping voltage formula

$V_0 = hf - \phi_{col}$ In a lecture, I was give the above formula for stopping voltage. It seemed a little simplified and weird to me as the LHS is in volts but the RHS is in electron volts. I did a ...

Why emission of an electron does not depend on light's intensity?

There's something that confuses me about the photoelectric effect. In an article I read, it's stated that the emission of an electron does not depend on the light's intensity. I'm not sure on which ...

What happens to photon in photoelectric effect

In photoelectric effect, when the photon gives energy to the electron, then what happens to itself? Where does it go? For me the photon must take the place of electron after the electron escapes the ...

The polarization filter does not work

I am working in Conduction phenomena Photo-conductivity Experiment. Here the experiment guide . The aim is to measure the photocurrent $I_{Ph}$ as a function of the voltage $U$ at a constant ...

Photoelectric current vs anode potential

Attached is the graph of photoelectric current vs Anode potential as given in my book for same intensity and different frequencies of incident light for the same metal(hence same work function). In ...
General textbooks introduce the photoelectric effect as the Einstein's formula $$hf=hf_0+E_c(max)$$ and where $E_c=mv^2_e/2$ is the kinetic energy maximum value, the work function is $eV_0=hf_0$, and ...
