C)Quality and quantity of radiation depends on the properties of the material only
D)All substances emit radiation the quality and quantity depends on the absolute temperature and the properties of the material composing the radiating body
E)Bodies black in colour are known as black bodies

Question

Quizplus · Accepted Answer

All substances emit radiation, and the quality and quantity of this radiation depend on both the absolute temperature of the substance and the specific properties of the material composing the radiating body. This principle is a fundamental concept in thermodynamics and electromagnetic theory, reflecting the behavior of real-world materials under varying thermal conditions.
