I need some explanation to present about light quanta.

Solutions

Expert Solution

Max Planck while studying the blackbody radiation was the first to suggest that the light changes occured in certain discrete equi-spaced units called quanta. Light quanta, also known as photons are the smallest discrete quantities of light, and each quanta/packet differs by an energy h, where h=Planck's constant and is the frequency. Thus, in each absorption or emission from one quantum state to another, energies of a multiple of h are emitted. This is true considering the particle nature of light. Further, the photons are elementary particles(bosons with integral spin). They have a zero rest mass, are chargeless and travel with the velocity of light in free space c. They also exhibit wave-particle duality.
