Enter the mass, velocity, and plank’s constant into the calculator to calculate the De Broglie Wavelength.

## De Broglie Wavelength Formula

The following equation is used to calculate a de broglie wavelength.

L = h / (m*v)

- Where L is the wavelength
- h is Plank’s constant (6.6262 X 10 & -34 Js)
- m is the mass (grams)
- v is the velocity (m/s)

## De Broglie Wavelength Definition

A De Brolie wavelength is a law that states all matter exhibits wave-like behavior and therefore you can calculate the wavelength using the equation.

## De Broglie Wavelength Example

How to calculate De Broglie Wavelength?

**First, determine the mass.**Measure the mass of the object or material.

**Next, determine the velocity.**Calculate the velocity of the matter.

**Finally, calculate the De Broglie Wavelength.**Calculate the wavelength using the formula above.

## FAQ

**What is a De Broglie Wavelength?**

The De Broglie Wavelength is a fundamental concept in quantum mechanics that states that all matter exhibits wave-like behavior, and therefore has a wavelength associated with it.

**How is De Broglie Wavelength calculated?**

The wavelength is calculated using the mass of the particle, velocity, and the Plank’s constant.
