The law stating that good emitters are good absorbers is known as [A] Kirchhoff’s law. This principle, formulated by Gustav Kirchhoff, states that the efficiency of radiation emission and absorption at a specific wavelength is equal for a given material. It is a fundamental concept in thermodynamics and electromagnetic theory, applicable across various scientific disciplines. Kirchhoff’s law plays a crucial role in understanding the behavior of thermal radiation and the equilibrium between emission and absorption processes in materials. It has significant implications in fields such as astrophysics, spectroscopy, and thermal engineering. By establishing a relationship between emission and absorption properties, Kirchhoff’s law provides valuable insights into the thermal behavior of materials and electromagnetic radiation. Therefore, option [A] accurately represents the law that states “good emitters are good absorbers”.
