Dual Nature of Radiation and Matter

Question:

Wavelength of matter wave is independent of:

Options:

momentum

charge

velocity

mass

Correct Answer:

charge

Explanation:

The correct answer is Option (2) → charge

The wavelength of the matter wave (De-brogile wavelength) is given by the equation, $λ=\frac{h}{mv}=\frac{h}{P}$

where,

h = plank's constant

P = momentum of matter wave

m = mass

v = velocity
