17.2 科学的转折光的粒子性（17.2. The turning point of Science the particle of light） 17.2 Science: turning the particles of light The new curriculum requirements. (a) knowledge and skills 1. through the experiment to understand the experiment law of photoelectric effect. 2. know Einstein photoelectric equation and its significance. 3. understand the Compton effect, understand the photon momentum (two) the process and methods Experience the process of scientific inquiry, understanding the significance of scientific inquiry, try to study physics problems using scientific inquiry, verify the physical laws. (three) the emotion, attitude and values The marvels and harmony of nature, the development of scientific curiosity and thirst for knowledge, to explore the mysteries of nature, to experience the hardships and happiness of exploration of natural law. Experiment of the teaching focus on the photoelectric effect. * Einstein photoelectric equation teaching difficulty and significance This teaching method of teachers inspire and guide students to discuss and exchange. * teaching equipment: slides, multimedia teaching equipment Class for 2 hours. The teaching process. (a) the introduction of new curriculum Question: a review of the previous study, summed up the development process of human understanding of the nature of light? (Multimedia Courseware projection, see.) Back, thinking, and answer. Listen to the teacher, comment. The interference and diffraction of light that light is an electromagnetic wave, polarization phenomenon shows light or shear wave. In 1860s, Maxwell also established from the theory of electromagnetic wave nature of light. However, it is beyond all expectations, just as people think when the wave theory of light seems to be very perfect, and found that the new phenomenon cannot be explained by wave phenomenon -- photoelectric effect. Study on this phenomenon and other related issues, and make a nature to light understanding has been developed. (two) a new les
