De Broglie Wavelength Formula

Introduction to De Broglie Wavelength Formula

The De Broglie wavelength formula, also known as the matter wave formula, relates the wavelength (λ) of a particle to its momentum (p) and Planck's constant (h).

Mathematical Background:

In quantum mechanics, particles exhibit both wave-like and particle-like properties. Louis de Broglie proposed that particles, such as electrons, have a wavelength associated with them. The De Broglie wavelength formula is derived from this idea, representing the wavelength of a particle with momentum.

Parameter Usage:

• λ = wavelength of the particle
• h = Planck's constant (6.626 x 10^-34 Js)
• p = momentum of the particle

Output:

• λ = calculated wavelength of the particle

Data Validation

The momentum (p) must be greater than zero for the calculation to be valid.

Practical Applications:

The De Broglie wavelength formula is fundamental in understanding the wave-particle duality and has practical applications in various fields of physics, including electron microscopy, quantum mechanics, and solid-state physics.
