I've been asked to find the value of c and the probability that the electron is located in the range of x=-1 and x=1.

2. Relevant equations

See Graph below

3. The attempt at a solution

|ψ|[itex]^{2}[/itex] graph http://img35.imageshack.us/img35/6663/psisquare.png [Broken]

As mentioned by ehild the graph is not drawn with correct scale (my carelessness, which caused all my problems)

For part a) I need to find value of C. Which I have found to be 0.577 but the answer seems wrong, I have done this by drawing a |ψ|[itex]^{2}[/itex] graph (which is almost the same except there are no negative y values. I have found c by making the area underneath |ψ|[itex]^{2}[/itex] equal to 1. Since the two smaller square in -1to -2 and 1 to 2 are exactly half I tried to find c by making the graph a rectangle with L=3nm given area must equal 1, width must equal [itex]\frac{1}{3}[/itex]. Hence I got a value for c which is [itex]\sqrt{\frac{1}{3}}[/itex] = 0.577

For part b I am asked to fin probability of electron being in x=-1 and x=1 nm. My answer was 0.666 (0.7 as I have been asked to answer in one significant figure) but this seems wrong too.

Anyone able to tell me where I have made mistake?

Thanks
