If I calculate the speed of an electron I know how fast it flies around. If I calculate it´s position I know where to find it. What information do I get if I calculate the wavelength (using wavelength=h/impulse)?

Question

anonymous · Answer

speed.. i think!!.. cause you are finding the wave property!

Why do I get via the wavelength some information about the speed of the particle?

anonymous · Answer

because if you use your debroglie equation.. you ll see the wavelength is related to the voltage through which your electron was accelerated and using that.. you can find out the velocity!

Ok, but this trick only works for charged particles. What does it say about a neutron? Also something about the speed or the kinetic energy?
