Question
What is the significance of electromagnetic wave theory of light?
Solution
- Maxwell (1864) proved that light is an electromagnetic wave which is transverse in nature carrying electromagnetic energy.
- He could also show that no medium is necessary for the propagation of electromagnetic waves.
- All the phenomenon of light could be successfully explained by this theory.
- Nevertheless, the interaction phenomenon of light with matter like photoelectric effect and Compton effect could not be explained by this theory.
