A particle is represented by the following wave function:
| ψ(x) =0 | x<−1/2 | |
| ψ(x) =C(2x + 1) | −1/2 < x < 0 | |
| ψ(x) =C(−2x + 1) | 0 < x < +1/2 | |
| ψ(x) =0 | x > +1/2 |
(a)Evaluate the probability to find the particle between x=0.19 and
x=0.35.
(b) Find the average values of x and x2, and the
uncertainty of x:
Δx=√(x2)av-(xav)2
| xav= | |
| (x2)av= | |
| Δx = |
