1. The problem statement, all variables and given/known data a. Does the photoelectric effect take place if mercury is illuminated with UV light with a wavelength λ = 300 nm? The cutoff wavelength for mercury is 250 nm. 2. Relevant equations ft= WF/h(planks constant) E=h(f) 3. The attempt at a solution im not sure how to start this because the work function is not given and neither is the frequency i know that i can get the work function if i have the frequency by multiplying it with planks constant, but im not sure how to get it with just the wavelength.
