Well, it seems that light has a wave form, so if a do this you can now see how you are getting an interference pattern.

看来光线是有波形变化的，这样一来你可以看到相互干扰模式是怎样产生的。

Fringes are formed when the optical difference (OPD) between a reference wave front and a test wave front based on the interference of light is an integral multiple of the illuminating wavelength.

测试中，当测试波前相对于参考波前的光程差是照明波长的整数倍时形成干涉条纹，由此而形成的二维图就是干涉图像。

How to improve the measurable accuracy of wavelength of light wave in biprism interference of light is discussed in this paper, and a simple, efficient experimental way is derived.

该文就提高双棱镜干涉测波长的测量精度问题展开探讨，并提出一种简单而有效的实验方法。

When light is in a wave form, it is subject to interference and disruption, often in predictable ways.
