To find the De Broglie wavelength of an electron moving at a speed of
, we can use the De Broglie equation:
where:-
is the De Broglie wavelength,-
is Planck's constant (
),-
is the mass of the electron (
),-
is the speed of the electron (
).Now, plug in the values:
So, the De Broglie wavelength of the electron is approximately
.
