An electron and a photon each have a wavelength of 1.50 nm. Find (i) their momenta, (ii) the energy of the photon and (iii) kinetic energy of the electron.

Explanation

To solve the problem step by step, we will calculate the momentum of both the electron and the photon, the energy of the photon, and the kinetic energy of the electron.

### Step 1: Finding the Momentum

**Formula:**
The momentum \( p \) of a particle can be calculated using the formula:
\[
p = \frac{h}{\lambda}
