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. If an object isn't moving, no external force acts on it. No it is always not true, there would be balanced forces which cancel each other out leaving no net force. Example:
What is Conductors and insulators Conductors - one or more electrons from each atom in solid can move freely by body conducting electric charge (metals) Insulators - electro
