Einstein’s Photoelectric Equation

Science > Physics > Photoelectric Effect >Einstein’s Photoelectric Equation In this article, we shall, derive Einstein’s photoelectric equation and study its use to verify the characteristics of the photoelectric effect of light. Wave Nature of Light: Christian Huygen’s proposed that the light is propagated in the form of a wave. But this theory has a […]
