The History of Photoelectric Effect Research and the Discussion of

Measuring Plank Constant Using Photoelectric Effect Methed

Abstract: This article aims to overall introduce the history of Photoelectric Effect research ,and give a systematic discussion abou½t the gist and error origin of measuring Plank Constant using Photoelectric Effect methed .This article introduces the history of Photoelectric Effect research firstly, including the elaboration of Hertz, Lenard, J.J.Thomson, Einstein and Millikan, of Whom have studied the Photoelectric Effect and have got some conclusions on it. Next it aims to elaborate the experimental error ☠origin and processing method of measuring Plank Constant using Photoelectric➳ Effect methed after introducing the experimental principle in detail. Finally the article elaborates the theoretical meaning and practical application of Photoelectric Effect .

Key words: Photoelectric Effect;Pl，anck Constant;Einstein Photoelectric equation;work function
