Label each of the following photons as ones that can or cannot be absorbed by this atom without ionizing the atom. The value stated is the energy of the photon is 9.0x10-19J.
a) 6.00×10-19J
b) 1.20×10-18J
c) 1.10×10-18J
d) 2.00×10-19J
e) 1.00×10-19J
Homework Answers
A photon is absorbed as it strikes an atom but it ionizes the atom if and only if its energy is greater than the ionization energy of the atom.
As mentioned, the ionization energy here is 9.0x10-19J.
a) 6.0x10-19 < 9.0x10-19
b) 1.20x10-18 < 9.0x10-19
c) 1.10x10-18 < 9.0x10-19
d) 2.0x10-19 < 9.0x10-19
e) 1.0x10-19 < 9.0x10-19
THerefore, b and c can be absorbed without ionizing the atom.

A photon with frequency 9.996 x 10^14 Hz strikes a slab of lead and is absorbed without freeing an electron. a) If the frequency of that photon is the threshold frequency for lead, calculate the work function for lead. Express your answer in eV. b) Assume a photon of wavelength 200 nm strikes the lead, freeing an electron. Calculate the maximum kinetic energy (in Joules) of the liberated electron. c) Calculate the de Broglie wavelength of the emitted electron. You...
