Thread: Narrow band light interference (?)

Peace be upon you,

The name is Yair, Israel, 26
I build LED grow lights for a living/hobby *LINK REMOVED*
I am NO physicist and my math skills are probably in the 10th grade ballpark.
Please do correct my terminology/understanding if anything doesn't coincide with the truth.

To the point,
I generally use 4 wavelengths (nm) of LEDs in my lamps - 660, 620, 440, 400
Each LED diode is outfitted with a 120 degree lens.
If I place 2 diodes of 440nm and 660nm, 1cm apart, where their beams cross, will I get only these 2 wavelengths on a spectrometer (which I don't own) or will there be a "blend" of some sort.

Thanks in advance!

Love peace and unity,
Yair

You will have the two wavelengths separately, if you use a spectrometer (or diffraction grating, or prism).
