Consider the electron wave function

                                            

where x is in nm.
a. Determine the normalization constant c.
b. Draw a graph of |ψ(x) |² over the interval -5 nm < x < 5 nm. Provide numerical scales on both axes.
c. Draw a graph of |ψ(x) |² over the interval -5 nm <  x <  5 nm. Provide numerical scales.
d. If 106 electrons are detected, how many will be in the interval -1.0 nm <  x <  1.0 nm?
