Question

What are the limitations of electromagnetic wave theory?

Answer 1

Answer:

The quantum nature of light was not part of the wave theory. In fact the energy of a quantum of light is directly proportional to the wave frequency. This limits the number high energy photons and therefore the distribution of radiant energy to the ultraviolet (short wavelength) end of the spectrum.

Answer 2

$\boxed{\boxed{\huge{\bf{Answer}}}}$

Limitations of Electromagnetic Wave Theory.

• This theory not explained why Change in colour is observed on heating a perfectly Black body.

Black body radiation - On heating a perfectly Black body , the energy of all frequency are emitted, which are called the black body radiation.

• This theory not explained the phenomena of photoelectric effect.

Photoelectric Effect - The emotion of photoelectron from any metal surface when light of suitable frequency falls on it is called photoelectric effect.
