Thus light, which was hitherto known to be a wave, was now known to have a dual character - that of a wave and a particle. Let us assume that k = iκ in a complex exponential plane wave, where κ is real: ψ = exp[i(kx − ωt)] = exp(−κx − iωt) = exp(−κx) exp(−iωt). (9.19) The wave function doesn’t oscillate in space when K = E −U < 0, but grows or decays exponentially with x, depending on the sign of κ. Our library has a good collection of them for you to explore.
