Atomic Model and Wave-Particle Duality

Photo-electron emission Einstein’s theory (1905)FromIt is clear thatK = hν – φ > 0,a) K max is independent of the intensity of the light.K max can be determined by the stopping reversedpotential:K max = e V s = hν – φa) No photoelectric effect when ν < ν 0 .This was confirmed by Millikan in 1915.
