What is the de broglie wavelength of an electron under 150 v acceleration?

Answer : The De Broglie wavelength of an electron is

Explanation :

According to de-Broglie, the expression for wavelength is,

The formula used for kinetic energy is,

The kinetic energy in terms of momentum will be,

p = m v

or,

As we know that,

where,

'q' is charge of electron and 'V' is potential difference.

So,

The de Broglie wavelength of the electron will be:

  .........(1)

where,

h = Planck's constant =

m = mass of electron =

q = charge of electron =

V = potential difference = 150 V

Now put all the given values in equation 1, we get:

conversion used :

Therefore, the De Broglie wavelength of an electron is
