Concept explainers
How the wavelength of the electron change, if the momentum of the electron were doubled.
Answer to Problem 6Q
Solution:
It would be halved.
Explanation of Solution
Given:
Momentums of an electron were doubled.
According to de Broglie’s concept,
The wavelength of a material particle is inversely proportional to its momentum.
Therefore, if an electron’s momentum is doubled, then de Broglie’s wavelength of electron becomes half to its initial value.
