Derive the relation between the wavelength `(lambda)` of the de broglie wave and kinetic energy `(E )` of a moving particle

Explanation

To derive the relation between the wavelength (λ) of the de Broglie wave and the kinetic energy (E) of a moving particle, we will follow these steps:

### Step 1: Write the expression for kinetic energy
The kinetic energy (E) of a moving particle is given by the formula:
\[ E = \frac{1}{2} mv^2 \]
where \(m\) is the mass of the particle and \(v\) is its velocity.
