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;Planck Constant;Einstein Photoelectric equation;work function.
