An object in <u>black</u> emits radiation at the same rate it absorbs solar energy
Explanation:
All body emits radiation following their temperature. E.g. colder bodies emit radiations with a longer wavelength, while the hot bodies emit radiation with short wavelength and higher frequencies.
A black body can be considered as an ideal body that absorbs all the energy incident on it and then emits all the radiation absorbed in a continuous spectrum depending on its temperature. In nature, stars behave similarly to black bodies. They emit all the radiation in a continuous spectrum depending on temperature. E.g. Cooler stars emit wavelength in the red and infra spectrum, while high-temperature stars emit lights in blue and UV wavelength
