De Broglie Wavelength
de Broglie wavelength of particle momentum p is:
Select the correct option:
Solution
h/p
Louis de Broglie hypothesized that all matter exhibits wave-like properties. The wavelength (λ) associated with a particle of momentum p is: λ=ph where h is Planck's constant.
- For a particle of mass m and velocity v, p=mv, so λ=mvh.
- This duality is only noticeable for microscopic particles like electrons due to the extremely small value of h.
