BSC PHYSICS Chapter Notes -Physical Constant, Mks System Of Units, International System Of Units
Document Summary
Planck"s constant is a physical constant in physics. It defines the behavior of particles and waves on the atomic scale along with the particle aspect of light. Planck"s constant is the physical constant that relates the energy carried by a single photon to its corresponding frequency. Represented by h and measure using j. s in the si system and ev. s in the mks system. The value of planck"s constant has got prime importance in quantum mechanics. Defenition::a fundamental constant, equal to the energy of a quantum of electromagnetic radiation divided by its frequency. The values of planck"s constant or value of h is experimentally validated. Value of h in si units h = 6. 6260715 10-34 j. s. Value of h in meter-kilogram-second(mks) units h = 4. 135667662 10-15 ev. s.
