What is meant by De Broglie Wavelength?
The De Broglie Wavelength is the wavelength at which an object's momentum and mass are related. The wavelength of de Broglie and the object force are inversely related. The de Broglie wavelength equation depicts the relationship between the particle's nature and the body's nature.
De Broglie's Formula
A beam of particles of a certain mass can act as a matter wave, according to de Broglie. Its wavelength is proportional to the particle's mass and velocity:
λ = h/mv
- Where m is the mass of the particle
- v is the particle's velocity, and
- h is the plank's constant i.e. h = 6.6261*10-34 Js

De Broglie Wavelength Examples
Question 1: Determine the wavelength of an electron travelling at 2*106ms-1?
The electron's velocity is v = 2*1066 ms-1
m =9.1*10-31 Kg is the mass of an electron.
h = 6.62607015*1034 Js, Planck's Constant
= h/mv gives us the de-Broglie wavelength.
= 6.62607015×10-34 /(2×106)(9.1×10-31)
λ = 0.364×109m

FAQ’s on De Broglie Wavelength Calculator
1. Which has a faster speed for the same de Broglie wavelength: the electron or the proton?
The particle's de-Broglie wavelength is the same. As a result, their momentum will be balanced. The product of mass and velocity is momentum. As a result, the speed of a given particle is inversely proportional to its mass. A proton with a larger mass will travel slower, while an electron with a smaller mass will travel faster.
2. How do you determine a wave function's de Broglie wavelength?
The de Broglie wavelength is equal to h/p, and the de Broglie relations are equal to h/p and f = E/h, respectively.
3. At 100 eV, what is the de Broglie wavelength of an electron in?
At 100 eV, what is the de Broglie wavelength of an electron? (b) 1.6 1017 J = K = 100 eV. = h/p = h/2mK = 0.123 nm, according to de Broglie.
4. What is the de-Broglie wavelength in terms of heat?
The average de Broglie wavelength of the gas particles in an ideal gas at the specified temperature is comparable to the thermal de Broglie wavelength.
