"If light rays are particles, then their refraction can be precisely calculated, the next day's calculation comprised over five thousand three hundred groups, the constant obtained is approximately..."
"Between one and one-quarter to one and one-third...."
Seeing this.
Xu Yun couldn't help but bite down hard on his back teeth, trying to maintain his composure.
Yet despite this, his fingers continued to tremble slightly.
The reason is none other than because of Old Jia and others...
They really did an amazing job this time.
It is well known.
In Fourier optics, spherical and planar waves can represent any complex wave.
Complex function = a DC zero-level Fourier term + higher-order Fourier terms.
Which means.
Spherical and planar waves are the fundamental solutions to the wave equation.
Among them, the complex amplitude of a planar wave can be represented as aexp[jk(xcosα+ycosβ+zcosγ)].
cosα²+cosβ²+cosγ²=1, this is the direction cosine of a planar wave.
