State how de-Broglie wavelength `(lambda)` of moving particles varies with their linear momentum (P).

Explanation

To determine how the de Broglie wavelength (λ) of moving particles varies with their linear momentum (P), we can follow these steps:

### Step 1: Understand the de Broglie Hypothesis
The de Broglie hypothesis states that every moving particle or object has an associated wave. The wavelength of this wave is given by the de Broglie wavelength.

### Step 2: Recall the Formula
The relationship between the de Broglie wavelength (λ) and the linear momentum (P) is given by the formula:
\[ \lambda = \frac{h}{P} \]
