Our eyes can't see that light's very short wavelengths.

我们的眼睛看不到光的非常短的波长。

Light's momentum is equal to the Planck constant divided by the light's wavelength.

光的量子等于普朗克常数 除以光的波长。

Exactly how this diffraction pattern looks, depends on the spacing of the slits and the light's wavelength.

这种衍射图案的外观究竟如何， 取决于狭缝的间距和光的波长。
