According to wave-particle duality, the De Broglie wavelength is a wavelength manifested in all the objects in quantum mechanics which determines the probability density of finding the object at a given point of the configuration space. The de Broglie wavelength of a particle is inversely proportional to its momentum.

What exactly is de Broglie wavelength?

The de Broglie wavelength of a particle indicates the length scale at which wave-like properties are important for that particle. De Broglie wavelength is usually represented by the symbol λ or λdB. For a particle with momentum p, the de Broglie wavelength is defined as: λdB = h/p.

What is the formula for de Broglie wavelength?

Sample Problem: de Broglie Wave Equation

Apply the de Broglie wave equation λ=hmv λ = h m v to solve for the wavelength of the moving electron.
