प्रश्न
Explain the term ‘wave-particle duality' of matter.
उत्तर
- De Broglie proposed that if radiant energy (light) has both the wave nature and particle nature, then particle (matter) must have a wave associated with its motion.
- ii. He believed that energy and matter must have some symmetrical character. This gave rise to the concept of the wave-particle duality of matter.
- Material particles show wave-like nature under certain circumstances. This phenomenon is known as wave-particle duality of matter.
