First, the teaching objectives 1. Knowledge requirements 1 know the phenomenon of light reflection; 2 know the definition of normal, incident angle, reflection angle; 3 understand the law of light reflection; 4 know the specular reflection and diffuse reflection. 2. Ability requirement 1 uses the law of light reflection as the optical path diagram; 2 distinguishes between specular reflection and diffuse reflection. 3. Moral education requires students to learn their interest by observing optical phenomena, doing optical experiments, and training students to use experimental methods.
