Inverse Square Law(平方反比定律)是物理学中描述物理量随距离增大而按平方反比关系衰减的规律。它广泛应用于光学、电磁学、声学等领域,解释了如光强、引力、电场强度等随距离变化的特性。下文将从定义、数学表达、具体应用及适用范围展开说明。 1. 定律的定义与数学表达 平方反比定...

The reasoning for the inverse square law is geometric in nature. As light is emitted from a point (or sphere) like from the Sun and travels toward a receiving surface, the initial quantity of photons is spread out over an increasingly larger spherical area with distance. We can envision the...
