Electromagnetic Spectrum
We will take a deeper look into the electromagnetic spectrum and .
Part1: terminology.
key takeaways: PAR is not how many mol or µmol. PAR only defines the range from 400-700nm. Extended versions of PAR (including infrared and UV have different names) ePAR (extended PAR) PBAR- Photo Biological Active Radiation and even More.
Don't forget: not all radiation is visible.
UVB / Far-red are visible, but the eye is less sensitive, and therefore it seems less bright.
Radiation at 860nm (infrared) is heat! You can feel it but not see it!
