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
Q. Define: Electric flux. Give its unit. The electric flux is described as the total number of electric lines of force crossing through the given area and its unit is Nm 2 C-1
Forces: If a Force is applied to a body, it will cause that body to move. A body that is already moving will change its speed or direction. Note that the term 'change its spe
