Objects at a temperature of 300 K (Kelvin) emit thermal radiation most intensely in the infrared region of the electromagnetic spectrum. Specifically, the peak intensity of the radiation corresponds to a wavelength around 10 micrometers, which falls within the mid-infrared range. This is commonly referred to as blackbody radiation, and it follows Planck's law of radiation. The exact peak wavelength depends on the temperature of the object according to Wien's displacement law.
