Please explain and solve
(a) A sample of Ca is irradiated with green light. Are electrons ejected? Justify.
(b) A sample of Ca is irradiated with light of wavelength 4.10 x 10^-7 m, and electrons are ejected. What is the speed, in m/s, of these electrons?
Please see the attached file for detailed solution.
a) first find the energy ...
The solution is comprised of detailed explanations of photoelectric effect of calcium. It shows the step-by-step calculation of the speed of the ejected electrons when the incident photon energy is larger than its work function.
