摘要
利用D’Alembert公式对行波在端点的反射进行了讨论,结果表明:光波从光疏介质射入光密介质在其界面反射时存在半波损失,而声波在反射表面不存在半波损失.
The D Alembert s formula is used to discuss the reflection property of the traveling wave at the endpoint.The results indicate that there exists the loss of half-wave when the light enters optically denser medium from optically thinner medium,but there is no loss of half-wave on the surface of the reflection for the sound wave.
