Relativistic corrections become neccssary when the expression for the kinetic energy `1/2mv^2` , becomes comparable with mc
2, where m is the mass of the particle. At what de Broglie wavelength will relativistic corrections become important for an electron?
Options:
(a) λ =10nm
(b) λ =10–1nm
(c) λ =10–4nm
(d) λ =10–6nm
