The mass of an electron is `9.1 xx 10^(-31) kg`. If its kinetic energy is `3.0 xx 10^(25) J`, calculate its wavelength.

Explanation

To calculate the wavelength of an electron given its mass and kinetic energy, we can follow these steps:

### Step 1: Write down the formula for kinetic energy
The kinetic energy (KE) of an object is given by the formula:
\[ KE = \frac{1}{2} m v^2 \]
where:
- \( KE \) is the kinetic energy,
- \( m \) is the mass of the object,
...
