Step 1:
I'll solve this problem by explaining the de Broglie wavelength formula step by step:

Step 2:
: Definition of De Broglie Wavelength

The de Broglie wavelength formula relates the wavelength of a particle to its momentum. It was proposed by Louis de Broglie in 1924 as a fundamental concept in quantum mechanics.

Step 3:
: The Formula

- $$p$$ is the momentum of the particle
The de Broglie wavelength formula is expressed as: Where:

Step 4:
: Key Insights

- This formula shows that all matter has wave-like properties - The wavelength is inversely proportional to the momentum - Smaller particles or particles with higher velocity will have shorter wavelengths

Step 5:
: Units and Interpretation

- Planck's constant ($$h$$) is in J·s
- Momentum (p) is measured in kg·m/s

Final Answer

The de Broglie wavelength formula is \lambda = \frac{h}{p}, which relates a particle's wavelength to its momentum.
