When light of wavelength 350 nm is incident on a metal surface, the stopping potential of the photoelectrons is measured to be 0.500 v. what is the work function of this metal? (c = 3.00 × 108 m/s, h = 6.626 × 10-34 j ∙ s, 1 ev = 1.60 × 10-19 j) 3.05 ev 4.12 ev 3.54 ev 0.500 ev

Julia would be observing a. static electricity was caused by her sweater rubbing against her shirt and transferring electrons. she didn't touch anything metal, so that would cancel out b.she most likely didn't rub her sweater against her hair either, so that cancels out c.she also didn't scoot across the carpet while trying to take her sweater off, that cancels out d.so that leaves a.a. is correct.
