Question

A moving particle may have wave motion if
A) its mass is very high
B) its velocity is negligible
C) its mass is negligible
D) its mass is very high and velocity is negligible

Answer 1

A moving particle may have wave motion if its mass is very high and velocity is negligible

Answer 2

Hi.

De Broglie's relation is:

$Wavelength=\frac{h}{p}$

Where h is Heisenberg's constant and p is momentum of the particle.

Larger the value of p, lesser will be wave nature.

So c) is correct option i.e its mass is negligible.
