When I stand out in the sun and feel its "warmth", I know that most of that warmth come from the infrared frequencies of the EM spectrum. But, do other frequencies of the ER spectrum contribute to "warmth"? Starting from the longest wavelengths: I'm sure that radio waves don't contribute. But how about microwave frequencies? Do some microwave frequencies get thru the atmosphere and contribute to the heat I am feeling? How about visible light - does it contribute to the heat I am feeling? Getting into the smallest wavelengths: do UV frequencies contribute some to the heat since I know some UV frequencies get thru (sunburn)? I'm pretty sure that x-rays and gamma rays don't contribute much because if they did I would probably be dead very shortly.
