The de Broglie wavelength of an electron is given by the equation:λ = h/pwhere:λ is the wavelengthh is Planck's constant (6.626 × 10^-34 J s)p is the momentum of the electronThe momentum of the electron is given by:p = mvwhere:m is the mass of the electron (9.11 × 10^-28 g)v is the velocity of the electron (3.66 × 10^6 m s^-1)Substituting the values of h, m, and v into the equation for the de Broglie wavelength, we get:λ = (6.626 × 10^-34 J s) / (9.11 × 10^-28 g * 3.66 × 10^6 m s^-1)= 1.99 × 10^-10 mTherefore, the wavelength of the electron is 1.99 × 10^-10 m.
