Answer:
The speed of an electron is 0.01908 m/s.
Explanation:
De-Broglie wavelength is given by:
where, = wavelength of a particle
h = Planck's constant =
m = mass of particle
v = velocity of the particle
Velocity of an electron = v
Mass of an electron =
Wavelength of electron is twice the displacement in seconds which is velocity of an electron.
Then.wavelength of an electron =
v = 0.01908 m/s
The speed of an electron is 0.01908 m/s.
