AI Generated Solution

To calculate the de Broglie wavelength of an electron given its kinetic energy, we can follow these steps: ### Step 1: Write down the formula for kinetic energy The kinetic energy (KE) of an electron is given by the formula: \[ KE = \frac{1}{2} mv^2 \] where \( m \) is the mass of the electron and \( v \) is its velocity. ...
