Consider a wave-packet of the formψ(x) =e−x2/(2σ2)describing the quantumwave function of an electron. the uncertainty in the position of the electron maybe calculated as ∆x=√〈x2〉−(〈x〉)2where for a functionf(x) the expectationvalues〈〉are defined as〈f(x)〉≡∫[infinity]−[infinity]dx|ψ (x)|2f(x)∫[infinity]−[infinity]dx|ψ (x)|2.calculate ∆xfor the wave packet given above.
