Question

Calculate the wavelength associated with an electron moving at a speed of

Answer 1

Answer:

At speeds much lower than the speed of light you would use the de Broglie wavelength equation:

λ = h/(mv)

However, a speed of 0.85c would require working with the relativistic version of the equation:

λ = [h/(mv)] √(1 - v2/c2)

h = Planck' constant

m = rest mass of electron
