Question

why black colour is good emitter of light?​

Answer 1

Answer:

Dark-colored materials absorb visible light better than light-colored materials. That's why the dark side of the card heats up first. The lighter side absorbs less of the incident light, reflecting some of the energy. Darker materials also emit radiation more readily than light-colored materials, so they cool faster.
