In an xray tube, a potential diff. of 70000v is applied across two electrodes. Electrons are emmited from cathode and acc. to anode, where x-rays are produced.
my question is if the photoelectric effect problems apply and how they apply.
(i.e use work function or E=hf)
questions on paper
a)find max frequency
b)find max momentum
Kmax = hf-Wo
