The threshold wavelength for the photoelectric effect for silver is 262 nm. (a) Determine the work function for silver. (b) What is the maximum kinetic energy of an electron emitted from silver if the incident light has a wavelength of 222 nm

a. The work function for silver is equal to 4.73 eV.

b. The maximum kinetic energy of an electron emitted from silver is .

Given the following data:

a. To find the work function for silver, we would use Einstein's equation for photon energy:

Mathematically, Einstein's equation for photon energy is given by the formula:

Where:

When the maximum kinetic energy of an electron is equal to zero (0), the work function of the electron is given by:

h =

Substituting the given parameters into the formula, we have;

Work function, = 4.73 eV

b. To find the maximum kinetic energy of an electron emitted from silver, if the incident light has a wavelength of 222 nm:

Maximum kinetic energy =
