MCQ
Louis de $-$ Broglie is credited for his work on:
- ATheory of relativity
- BElectromagnetic theory
- ✓Matter waves
- DLaw of distribution of velocities
✓
Answer
Correct option: C.
Matter waves
De Broglie, in his $1924\ PhD$ thesis, proposed that just as light has both wave$-$like and particle$-$like properties, electrons also have wave$-$like properties. Here he worked on matter waves.
