...so that the red end of the spectrum is passed and the rest of the spectrum is filtered out
If I apply a red filter, are Infrared, Microwave and Radio passed? and are Gramma ray, X-ray, Ultraviolet, Visible filtered out?
Does anyone have any suggestions?
Thanks everyone very much for any suggestions
