Wearing black at night...is it true that wearing a black t shirt on a hot night at night will make you cooler than a white t shirt? Has this got anything to do with blackbody radiation?
I would think it depends on a couple of things... how hot the surroundings are and whether it is 'black' at infrared wavelengths.pkc111 said:Wearing black at night...is it true that wearing a black t shirt on a hot night at night will make you cooler than a white t shirt?

A black t-shirt is a piece of clothing that is completely black in color, absorbing all wavelengths of light that hit it. A blackbody is an object that absorbs all incident electromagnetic radiation, regardless of wavelength or angle of incidence.
Black t-shirts and blackbodies appear black because they absorb all wavelengths of light that hit them, reflecting little to no light back to our eyes.
The relationship between black t-shirts and blackbodies is that both are capable of absorbing all wavelengths of light, with black t-shirts being a real-life example of a blackbody.
Black t-shirts and blackbodies are known to absorb and radiate heat more efficiently than other colors or objects. This is because they absorb all wavelengths of light, converting them into thermal energy and increasing the temperature of the object.
No, there are other objects that can also behave as blackbodies and absorb all wavelengths of light. However, black t-shirts are a common and easily accessible example of a blackbody. Other examples include black paint, asphalt, and outer space.
