Photoelectric effect

?
Define photoelectric effect
When a photon strikes a metal surface and if it meets the threshold frequency then an electron is emitted from the surface of the metal.e
1 of 6
Define work function
The minimum energy required to remove an electron from the surface of a metal.
2 of 6
Photoelectric effect equation
EKmax = hf - φ Maximum kinetic energy = plancks constant X (times) frequency - (minus) work function
3 of 6
y=mx+c for e=hf-φ
y axis equals maximum kinetic energy,gradient is plancks constant, x axis is frequency and negative work function is the y intercept
4 of 6
What is threshold frequency
The lowest frequency of electromagnetic radiation/photons that will result in the emission of Photoelectrons.
5 of 6
Threshold frequency equation
φ=hfo (fo is threshold frequency, h is plancks constant, φ is work function)
