#4.5.2a
(i) photoelectric effect, including a simple experiment to demonstrate this effect
Learners should understand that the photoelectric effect provides evidence for particulate nature of electromagnetic radiation.
(ii) demonstration of the photoelectric effect using, e.g. gold-leaf electroscope and zinc plate
#4.5.2b
a one-to-one interaction between a photon and a surface electron
#4.5.2c
Einstein’s photoelectric equation \(hf = ϕ + KE_{max} \)
#4.5.2d
work function; threshold frequency
#4.5.2e
the idea that the maximum kinetic energy of the photoelectrons is independent of the intensity of the incident radiation
#4.5.2f
the idea that rate of emission of photoelectrons above the threshold frequency is directly proportional to the intensity of the incident radiation.
