Hello Everyone,
Sunlight is composed of UV, visible and infrared (IR) over a wavelength range from ~290nm to ~2500nm.
When we are exposed to sunlight and feel hot, is it because of the absorption of energy at the visible wavelengths and FIR, i.e . infrared wavelength much larger than 2500nm? I don't think radiation in the range 700nm-2500nm produces a heating sensation in the human body. Or does it?
Thanks
