Answer:
λ=1.455 nm
You can use the de Broglie relation, since an electron has mass. You can use the. de Broglie relation, since an electron has mass. What is the speed of a photon in vacuum with a wavelength.
What is its kinetic energy? Assume the mass of the proton to be 1.673 x 10-27 kg.
λ = 5.107 x 10¯10 m
Solution:
1) Determine the speed of the neutron:
3.00 x 108 m/s divided by 500 = 6.00 x 105 m/s
2) Calculate the kinetic energy of the neutron (I used Joule for the energy unit):
KE = (1/2)mv2
KE = (1/2) (1.67493 x 10¯27 kg) (6.00 x 105 m/s)2
KE = 5.02479 x 10 ¯22 J
