Photoelectric effect post assessment problem 34

Postby Emily Mei 1B » Sat Oct 14, 2017 5:29 pm

If molybdenum is irradiated with 194 nm light, what is the maximum possible kinetic energy of the emitted electrons?

We're given in the last problem that that Molybdenum metal absorbs radiation with minimum frequency of 1.09x10^15 s^-1. I also calculated the minimum energy (E=hv) is 7.22 x 10^-9 J. In this problem, is the minimum energy the same value as the threshold energy?

Yes, they are the same. The threshold energy is the minimum energy.
