The dimension of momentum is, p = M 1 L 1 T - 1 From de Broglie equation, h p = λ [ h ] = [ p ] λ = M L 2 T - 1 The stopping potential is related to maximum kinetic energy of emitted electron as V s = K E m a x e = ML 2 T - 2 AT = ML 2 T - 3 A - 1 From Einstein's photoelectric equation, the work function ϕ has dimensions of energy ϕ = ML 2 T - 2
