Question

if the wavelegnth is equal to the distance travelled by the electron in one second 'then "lamda =
$\sqrt{h \div m}$
​

Answer 1

Answer:We know that Planck's constant divided by the momentum gives the wavelength of the particle,

If the distance traveled by the electron in one second, then the above equation changes as,

Therefore,   

By substituting the values of Planck's constant and mass of electron values, we get

Therefore

= 0.027m/s

The distance traveled by the electron is 0.027m/s or 2.7cm/s or 0.06mm/hr
