Quantum Theory of Light:
Wave theory failed to describe some new effects in 19th century. A German Physicist Max Plank gave theory about the nature of light.
1. Light is emitted from a source in tiny packets of energy or Quanta.
2. These energy packets or bundles of light known as Photon.
3.The light is emitted and absorbed in the form of Photons.
4.The energy possessed by a photon depends upon its frequency
When hydrogen atom is excited, it returns to its normal unexcited (or ground state) state by emitting the energy it had absorbed previous. This energy is given out by the atom in t
Define: Electric potential. The electric potential in an electric field at a point is define as the amount of work done in moving a unit positive charge from infinity to that
