## 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.

## Meta Description:

The De Broglie wavelength formula relates the wavelength of a particle to its momentum and Planck's constant. This calculator helps find the wavelength.
