The Formula Explained

The formula used for the de Broglie wavelength is:

λ = h / (m * v)

Where:

λ = wavelength
h = Planck's constant (6.62607015 × 10^-34 m^2 kg / s)
m = mass of the particle
v = velocity of the particle

Glossary of Terms

Mass (kg): The mass of the particle in kilograms.
Velocity (m/s): The speed of the particle in meters per second.
Wavelength (m): The de Broglie wavelength of the particle.

Frequently Asked Questions (FAQ)

What is the de Broglie wavelength?

The de Broglie wavelength is a fundamental concept in quantum mechanics, representing the wavelength associated with any moving particle.

Why do we use the de Broglie wavelength?

It helps in understanding the wave-particle duality of matter, crucial for explaining phenomena at the quantum scale.

Can the wavelength be measured directly?

In most cases, the de Broglie wavelength is calculated rather than measured directly.

How does mass affect the wavelength?

Higher mass results in a shorter wavelength, assuming the velocity is constant.

What happens if the velocity is zero?

If velocity is zero, the particle does not have a de Broglie wavelength as it's not in motion.
