1. The problem statement, all variables and given/known data 1. Explain the effects To the photocurrent as the light intensity increases To the photocurrent as the frequency of the light is increased To the speed of the photoelectrons as the radiation intensity increases To the speed of the photelectrons as the radiation frequency increases 2. Radiation with a frequency of 6.67 * 10^14 Hz is used to illuminate a photoelectric surface (W=2.50eV). The ejected electrons are now deflected by a perpendicular magnetic field (B=3.11*10^-5T). What is the maximum radius of these deflected electrons? [ANS: 5.57 * 10^-2m ] 2. Relevant equations Ek = hf-W W=hfo c=f (lambda - wavelength) 3. The attempt at a solution 1.a) more current b) nothing c) increases speed d) increases speed - i dont really know how do i solve this? some help here 2. I really have no idea i got E, from E=hf-W = 4.2221 *10^-20, but i dont know how to fuse B with E to find radius, maybe Fm=Fc? but so many unknowns.
