MCQs with answers on Planck constant Introduction: Planck constant is a universal constant and is a physical quantity invented in 1900 by the physicist Max Planck, the creator of the particle nature of light. Before the quantum law, classical physics interpreted the wave character of light, which could not explain the interaction of light with matter. MCQs of Planck's constant Planck's quantum theory proposed the quantum nature of electromagnetic radiant energies. Besides, it was the basic theory of quantum mechanics and explained the energy existence as tiny erratic bundles. This blog discusses MCQs of Planck's constant with descriptive answer explanations.

 Planck's constant of quantum theory Introduction to Planck's constant It is a fundamental physical quantity. Its magnitude and unit are independent of other physical quantities for measurements. It explains the particle nature of light on the atomic and sub-atomic levels. Thus, Planck's constant plays a vital role in quantum theory. It is a number that helps to calculate the energy of light. The symbol "h" denotes it. It is a constant value that does not change with time. So, it is a universal constant. The value of Planck's constant is 6.626 X 10 -34 Js in the SI system. Today's blog post topic is Planck's constant explanation. It covers definitions, units, values, and applications of Planck's constant.
