Answer:
Green coloured surface is a better radiator than shining silver surface.
Explanation:
Absorption is the phenomenon that tells that any body in th world absorbs a specific frequencies of light/heat/electromagnetic radiations.
Radiation is the exact opposite of absorption.
Radiation is the phenomenon that explains that every body radiates a specific frequencies of light/heat/electromagnetic radiations it has absorbed.
A black body is the best absorber and radiator because it can absorb and radiate most of the frequencies of light/heat/electromagnetic radiations.
White body is the poorest absorber and radiator of light/heat/electromagnetic radiations.
Silver is very close to a white body. Therefore it is a very poor radiator of light/heat/electromagnetic radiation.
Hence,
Green coloured surface is a better radiator of heat.
