Webb26 juli 2024 · When visible light and high frequency infrared radiation are absorbed by the surface of the Earth, the planet’s internal energy. increases and the surface gets hotter. WebbAll objects emit electromagnetic radiation that depends on their temperature. Hot objects glow red and very hot objects glow white hot, because they emit light as well as infrared. The hotter the object, the more electromagnetic radiation it emits and the higher the maximum frequencies. Warm objects, like radiators and human bodies, emit infrared.
