Calculate the velocity of electrons that form the same pattern as 450-nm light when passed through a double slit. The mass of an electron is 9.11 \times 10^{-31}~\text{kg}9.11×10 −31 kg.

The velocity of electrons is 1617.27 m/s.

Explanation:

Given that,

Wavelength of light,

Mass of an electron,

We need to find the velocity of electrons. It can be given by using De-Broglie wavelength such that :

So, the velocity of electrons is 1617.27 m/s. Hence, this is the required solution.
