Class 11 Chemistry Structure of Atom Electromagnetic spectrum

Electromagnetic spectrum

When all the electromagnetic radiations are arranged in order of increasing wavelengths, and decreasing frequencies the complete spectrum is called electromagnetic spectrum as shown below:


Limitations of this theory

 It failed to explain various phenomenons that are mentioned below:

  1. Black body radiations.
  2. Photoelectric effect.
  3. The variation of heat capacity of solids at different temperatures.
  4. The line spectra of atoms.
