Title: Could light have a third wave and perhaps project in a spiral?
Post by: Europan Ocean on 06/08/2019 18:03:40
Could it be that light or electromagnetic energy has a third wave, a diagonal, and that light may move or project forward in a spiral motion? Not simply a wave?

It doesn't need a 3rd wave to do that.

Telecommunications researchers have been experimenting with helical modulation of light:
- not just clockwise or anticlockwise circular polarisation (m= 1)
- but also using m= 0, 2, 3, etc
