DUAL NATURE OF LIGHT: DEVELOPMENT LEADING TO BOHR’S MODEL

There were so many factors, phenomenon that lead to the failure of Rutherford model:

  1. Dual nature of matter
  2. Atomic spectra

But before studying Bohr model, we need to learn electromagnetic radiations.

Newton said the corpuscles of light possess wave nature of light.

It was able to explain reflection, refraction etc. But failed to explain phenomenon of interface or diffraction. So, particle nature of light was considered.

Let us study about dual nature. It is electromagnetic theory, which was given by Huygens.This proved wave like character of

Light and tells us about wave motion. Wave motion is like if you throw stones, you will see a ripple that is wave.
