Answer

\frac{h}{mv}$$

To calculate the wavelength of an electron, we use the de Broglie wavelength formula: $\lambda = \frac{h}{mv}$ where: • $\lambda$ is the de Broglie wavelength • $h$ is Planck's constant ( $6.626 \times 10^{-34} \, J \cdot \text{s}$ ) • $m$ is the mass of the electron ( $9.109 \times 10^{-31} \, \text{kg}$ ) • $v$ is the speed of the electron ( $4.2 \times 10^7 \, \text{m/s}$ )

Step 1: Substitute the given values into the formula.
