在高中物理的很多资料中,都认为光子没有静止质量,这是按照爱因斯坦的狭义相对论得到的结论.否则,爱因斯坦的质能关系式将会导出光子具有无穷大的相对静止能量的理论结果.因此光子没有静止质量的结论似乎已经成为中学教师公认的事实.尽管理论分析得到光子静止质量是非常的微小, In many materials of high school physics, it is considered that photons do not have rest masses. This is based on Einstein’s special theory of relativity. Otherwise, Einstein’s relation of mass and energy will lead to the theory that photons have infinite stationary relative energy. As a result, the conclusion that photons do not have a resting mass seems to have become a fact recognized by middle school teachers. Although the theoretical analysis yields the photon rest mass is very small,
