光的波粒二象性是指光既具有波动特性，又具有粒子特性。科学家发现光既能像波一样向前传播，有时又表现出粒子的特征。因此我们称光为“波粒二象性”。
如何描述光的波粒二象性？
法国物理学家德布罗意在光的波粒二象性的基础上大胆推断：一切实物粒子都具有波粒二象性。
French physicist DE Broglie wave-particle duality of light based on the bold inference: all physical particles have wave-particle duality.
用光子计数仪作光强检测装置，通过测量衍射后的光子计数的空间分布来演示光的波粒二象性。
Using a photon counting apparatus as a device to measure light intensity, wave particle dualism of light is demonstrated by measuring photon distribution of double slit diffraction.
