Question:
(a) What is the energy in joules and electron volts of a photon of 420-nm violet light?
(b) What is the maximum kinetic energy of electrons ejected from calcium by 420-nm violet light, given that the binding energy (or work function) of electrons for calcium metal is 2.71 eV?
Strategy
To solve part (a), note that the energy of a photon is given by E= hf. For part (b), once the energy of the photon is calculated, it is a straightforward application of KEe = hf-BE to find the ejected electron's maximum kinetic energy, since BE is given.
