The wavelength of matter wave depends upon:

A. charge
B. velocity
C. momentum
D. mass
E. charge density

Choose the correct answer from the options given below:

B, C, D only

The correct answer is Option (2) → B, C, D only

De-Broglie wavelength (λ) of matter is -

$λ=\frac{h}{P}=\frac{h}{mv}$

where,

P = Momentum of particle

m = mass of particle

v = velocity of particle

∴ it depends upon momentum, mass and velocity.
