So I was reading THIS book on nano optics. It says that the maximum possible spread in the wavevector component k(The spread can occur for instance when the light field converges towards a focus, e.g. behind a lens.) is the total length of the free space wavevector k=2π/λ.
Can anyone please explain this to me?! Thanks.
