    According to the quantum of electromagnetism, Planck’s constant is considered to be the physical constant that relates the energy carried by a single photon to its corresponding frequency. It is represented by h and is measured in J.s that is SI system and eV.s in the MKS system.

    The value of Planck’s constant has a significant role in quantum mechanics.

    A fundamental constant, equal to the energy of a quantum of electromagnetic radiation divided by its frequency is called the Planck constant.

    Planck’s constant is used for explaining the behavior of particles and waves at an atomic level. Planck’s constant is one of the main causes for the development of quantum mechanics. It also used for measuring Planck length and Planck time.

    The values of Planck’s Constant or value of h is given by:

    h = 6.6260715×10-34 J.s
