The stopping potentials for light of frequencies ν_1 and ν_2 on a metal are V_1 and V_2. Planck's constant is given by

(C) (e(V_1 - V_2))/(ν_1 - ν_2). Concept. Einstein's equation at two frequencies: eV = hν - φ. Step 1. Subtract. e(V_1 - V_2) = h(ν_1 - ν_2). Step 2. Solve. h = (e(V_1 - V_2))/(ν_1 - ν_2). Answer. (e(V_1 - V_2))/(ν_1 - ν_2) (Option C).
