Question

What is the De-Broglie wavelength of the heavier particle?

Answer 1

1. The De-Broglie wavelength is given by, $\lambda =\frac{h}{mv}$ Where $m$ is the mass of the particle, $v$ is the velocity of the particle and $h$ is the Planck's constant.
2. Thus, the De-Broglie wavelength depends on two factors, mass, and velocity.
3. If two particles move with the same velocity then the De-Broglie wavelength is inversely proportional to its mass.
4. That is, the mass of the particle will be its wavelength and vice-versa.
5. Hence, the particle with a heavier mass will have less De-Broglie wavelength than the lighter mass particle.
