频闪照相是研究物体运动规律的常用方法,人民教育出版社现行高中物理教材中有5处涉及到频闪照相.频闪照相需要有B门的相机、频闪仪、暗室,并且拍摄对象与背景要有较大的对比度.一般学校没有这样的条件,中学物理教师也很少进行过频闪摄影. Strobe photography is a common method for studying the motion law of objects. People’s Education Press has 5 strobe photographs in the current high school physics textbooks. The strobe camera requires a camera with a b-door, a stroboscope, and a dark room, and the subject The background should have a large contrast. The general school does not have such a condition, and physics teachers in middle schools rarely perform strobe photography.
