Question
A metal with a work function of 2.40 eV is illuminated by a beam of monochromatic light. If the stopping potential is 2.5V, what is the wavelength of the light?
Answers
energy is .1ev
energy= plancks constant*c/lambda
change energy from ev to joules, then solve for lambda
energy= plancks constant*c/lambda
change energy from ev to joules, then solve for lambda
