A 480 nm laser beam is incident on two different metallic surfaces, one made of sodium (Na), the other of magnesium (Mg). If the respective work functions of these metals are 2.66 eV and 3.66 eV, will electrons be ejected by the 480 nm photons? If so, calculate the maximum KE the photoelectrons can have.

This question is for modern physics and wave and particle: (a) To how small a region must an electron be confined for borderline relativistic speeds – say, 0.05c – to become reasonably likely? (Ans: 3.9×10^−12m ) (b) On the basis of this, would you expect relativistic effects to be prominent for hydrogen’s electron, which has an orbit radius near 10-10? For a lead atom “inner-shell” electron of orbit radius 10-12m?
