The maximum wavelength of light that will cause ejection of a photoelectron in silver metal is 262 nm. What is the threshold energy or minimum energy, in J, required to eject an electron from silver?

a. 1.21 x

b. 7.59 x

c. 8.73 x

d. 1.31 x

e. 7.59 x


Establish the relationship of energy and wavelength then calculate the energy of a photon that is required to eject an electron with a maximum wavelength of 262 nm

Recall that the energy of a photon (E) is given by:
