The de Broglie wavelength

The de Broglie wavelength is a concept in quantum mechanics proposed by Louis de Broglie in 1924. It suggests that particles, such as electrons or even macroscopic objects, exhibit wave-like behavior. The wavelength, denoted by λ (lambda), is inversely proportional to the momentum of the particle. The formula for the de Broglie wavelength of a particle is:

$𝜆=\frac{ℎ}{𝑝}$

Where:

• λ is the de Broglie wavelength
• $ℎ$ is Planck's constant ($6.62607015\times 10^{-34}$ m² kg / s)
• $𝑝$ is the momentum of the particle

This concept has significant implications in understanding the behavior of particles at the quantum level and is fundamental to the principles of wave-particle duality in quantum mechanics.
