Question

In a photoelectric experiment, the collector plate is at 2.0 V with respect to the emitter plate made of copper (ϕ = 4.5e V). The emitter is illuminated by a source of monochromatic light of wavelength 200 nm. The maximum kinetic energy of the photo electrons reaching the collector is ----eV

Moderate
Solution

KEmax emitted =hcλϕ=12402004.5=1.7eVKEmax reached =1.7+2=3.7eV
