Formula and explanation
Formula: eU c = E(kmax) = h u - W₀ Applicable Conditions: Measuring the maximum initial kinetic energy of photoelectrons by applying a reverse voltage. Brief Explanation: The stopping voltage U c is the minimum reverse voltage that reduces the photocurrent to zero. eU c equals the maximum initial kinetic energy of the photoelectrons E(kmax).
