Correct option is A
The correct answer is (a) both particle and wave nature
Explanation:
- Subatomic particles such as electrons, protons, and neutrons exhibit both particle and wave-like properties, a concept known as wave-particle duality.
- This principle is a key feature of quantum mechanics, introduced by Louis de Broglie in 1924. He proposed that every moving particle or object has an associated wave nature, described by the de Broglie wavelength:
Where:
- λ = wavelength
- h = Planck’s constant
- m = mass of the particle
- v = velocity of the particle
This duality was later confirmed experimentally, especially with electrons (e.g., electron diffraction experiments).

Wave-Particle Duality in Practice:
- Electrons can diffract and interfere like waves (wave nature).
- Electrons also show discrete impacts on detectors (particle nature).
Applications:
- Electron microscopes work based on the wave nature of electrons.
- Quantum mechanics explains the behavior of atoms and subatomic particles using duality.
