Just going over all the topics before I crack on with past papers, I love the fact that there are no other papers scheduled around this paper, I can just focus on just physics!!
Can someone answer me why for electron scattering we use lambda=hc/E to determine wavelength rather than de broglie equation? I would have thought as its and electron we would have to use Lambda=h/mv, or are they the same thing but rearranged somehow?
Oh and am I right in thinking the reason electrons need to be fast enough for relativistic phenomena to come into play is because they only display wave like properties at this speed?
Thanks for any help!
