Calculate the de Broglie wavelength of an electron traveling at 2.0 x 10^8 m/s (me = 9.1*10^-31 kg).
6.9 x 10^-6 m
O 2.8 x 10^11 m
O 3.6 * 10^12 m

Explanation:

We have,

Speed of an electron is

It is required to find the De Broglie wavelength of electron. The formula for the De- Broglie wavelength is given by :

h is Planck's constant

m is mass of an electron

Plugging all the values we get :

So, the De-Broglie wavelength of an electron is
