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
what difference between these two laws
Kirkwood gaps (Kirkwood): Gaps in the asteroid belt, caused through resonance effects from Jupiter. Identical gaps exist in Saturn's rings, because of the resonance effects of
FORCE AND NEWTON'S LAWS 1. Ancient view objects tend to stop if they are in motion; force is needed to keep something motion. This was a natural thing to believe in beca
