ρ = hc / (wavelength)
ρ = hc / f
ρ = h / (wavelength)
- 10. Multiple Choice
How is the threshold frequency (work function) related to the photoelectric effect?
(choose as many correct answer as you can)
It is the maximum frequency of incident radiation needed to cause the ejection of atoms from anode
It is the minimum frequency of incident radiation needed to cause the ejection of electrons from the cathode
It is the minimum frequency of incident radiation needed to cause the ejection of atoms from anode
It is the frequency of incident radiation below which electron will be ejected from atom
