Question

Lighter is the particle or smaller is the velocity of a particle, ----------is the wavelength associated with it is smaller greater can t be defined none of these

Answer 1

greater is the wavelength

Answer 2

Answer: The correct answer is "greater".

Explanation:

The expression for De-broglie's wavelength is as follows;

$\lambda =\frac{h}{mv}$

Here, m is the mass of the object, h is Planck's constant and v is the velocity of the object.

The wavelength is inversely proportional to the mass and the velocity of the particle. If the velocity and the mass of the particle is smaller then there is greater wavelength. If the velocity and the mass of the particle is greater then lesser the wave characteristic is exhibited .

Therefore, lighter is the particle or smaller is the velocity of a particle, greater is the wavelength associated with it.
