Question:

What is the maximum kinetic energy in eV of electrons ejected from sodium metal by 3.1 x 102-nm EM radiation, given that the binding energy is 2.28 eV? Your answer should be a number with two decimal places, do not include unit.


Answers

solution → Energy of the EM radiation = E = he = 6.62x10 3430x10° eV 310 X10-9x11681619 = 19.86 x 10-26 er 4096 X10-26 = 4.00
