De Broglie Wavelength
de Broglie wavelength λ of particle momentum p is?
Select the correct option:
Solution
h/p
- De Broglie Hypothesis: Louis de Broglie proposed that matter, like light, exhibits wave-particle duality. For every moving particle, there is an associated wave (matter wave).
- Wavelength Formula: The wavelength (λ) associated with a particle of mass m and velocity v is: λ=ph=mvh
- Momentum (p): Here p=mv is the linear momentum of the particle.
- Scale: For macroscopic objects, h is so small that the wavelength is undetectable. For subatomic particles, it becomes significant.
