Who first proposed the light as an electromagnetic wave?
- AThomas Young
- BMax planck
- ✓James Clerk Maxwell
- DAlbert Einstein
✓
Answer
Correct option: C.
James Clerk Maxwell
In $1864$, Maxwell predicted the existence of electromagnetic waves, the existence of which had not been confirmed before that time, and out of his prediction came the concept of light being a wave, or more specifically, a type of electromagnetic wave. It is a wide intuition that Albert Einstein proposed the dual nature theory but is not correct.
