An electron and a photon each have a wavelength 1.00 nm. Find
(i) their momentum,
(ii) the energy of the photon and
(iii) the kinetic energy of electron.

Explanation

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

### Step 1: Calculate the Momentum
The momentum \( P \) of a particle can be calculated using the formula:
\[ P = \frac{h}{\lambda} \]
where:
