From the scattering of sunlight, Thomson found that the classical radius of the elec- tron is 2.82 × 10-15 m. If sunlight with an intensity of 470 W/m2 falls on a disk with this radius, estimate the time required to ac- cumulate 1.0 eV of energy. Assume that light is a classical wave and that the light striking the disk is completely absorbed. How does your estimate compare with the observation that photoelectrons are emitted within 10-9s?
