Answer #1

   = h/mv

    m       = 9.10938 x 10-28g

   = 35.7nm = 35.7*10-7 cm

     h           = 6.625*10-27 erg-sec

      = h/mv

   35.7*10-7 = 6.625*10-27/9.10938 x 10-28 * V

          v      = 6.625*10-27/9.10938 x 10-28 * 35.7*10-7

                  = 6.625/9.10938 *35.7*10-8

                   = 2.03*106 cm/sec

If the De Broglie wavelength of an electron is equal to 450 nm calculate the velocity of the electron. Assume that the electron's speed is non-relativistic. Tries 0/10 If the kinetic energy of an electron is 170 eV, calculate its De Broglie wavelength. For this non-relativistic electron you must first calculate its velocity from the general kinetic energy equation. Then you can find the De Broglie wavelength of the electron.
