疑点一 有人认为课本上对光的反射定律的叙述太啰嗦,是否可以把它直接简化成“反射角等于入射角”呢? 释疑 不能简化,光的反射定律由三句话组成,缺少任何一句都不能确定反射光线的空间位置,“反射光线跟入射光线和法线在同一平面上”,这是定律中的第一句话,由这句话可以 One doubt is that some people think that the textbook’s law of reflection of light is too ambiguous. Can it be reduced directly to “the angle of reflection equals the angle of incidence”? The suspicion cannot be simplified. The law of light reflection consists of three sentences, and any one of them is missing. Can not determine the spatial position of the reflected light, “reflected light with the incident light and the normal line in the same plane”, this is the first sentence in the law, from this sentence can
