SUMMARY
The discussion centers on calculating the number of electrons ejected, their energy in eV, and their velocity from a microjoule pulse of 500nm laser light, given that the work function of Rubidium (Rb) is 2.09 eV. The relevant equations provided include K.E = hv - (work function), v = speed of light / wavelength, and E = nhv. Participants emphasize the application of the photoelectric effect and encourage the use of these equations to derive the necessary values.
