Question

(b) A particle limited to the x-axis has the wave function $Psi = ax^2$ between $x = 0$ and $x = 1$; $Psi = 0$ elsewhere. (i) Find the probability that the particle can be found between $x = 0.55$ and $x = 0.75$. (ii) find the expectation value $<x>$ of the particle's position.

Step 1

Normalization ensures that the total probability of finding the particle anywhere in the space is 1. The normalization condition is given by the integral of the square of the wave function over all space being equal to 1. For our wave function, this means: \[ Show more…

A particle limited to the x-axis has the wave function ̘(x) = ax between x = 0 and x = 1, and ̘(x) = 0 elsewhere. Find the probability that the particle can be found between x = 0.55 and x = 0.75. Also, find the expectation value <x> of the particle's position.
