for sco The wave function of a particle is given as V000) = { 0, La expr-c) for x7o. Where a es constant a determine a so that this wave function is normalized ii) Sketch probability density il calculate the expectation value of ac in calculate uncertainty 4x
O 0 The wave function of a particle is given as Y) = a exp (-x) for no for xro where a = constant.
