(“calculate the wavelength of an electron traveling with a speed of 2.65 x 10^6 m/s?”)
———————————–
p = m v
m = 9.108383 x 10^(-31 kg)
v = 2.65 x 10^6 m/s
E = pc
E = energy of the electron
c = 3.0 x 10^8 m/s (the speed of light)
E = h c / lambda
h = 6.626 x 10^(-34) J sec.
lambda = wavelength
solve the equation for lambda and then derive the answer.
