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. For particles that have mass such like electrons quantum theory gives the relationship of wavelength to momentum by which of the following formulas, where h is Plancks constant,
Q. Illustrate that does the solar radiation contain a complete spectrum of all forms of electromagnetic radiation? Answer:- It is true that it does. It holds all the forms
if electrons are moving from east to west in a conductor is there a flow of current?
