Normalization Constant A

[PhyzicsOfHockey]

Homework Statement

The wave function of a particle is Y(x,t) = A e^-kx*e^-iwt for x greater than or equal too 0, and it is zero everywhere else. What is the numerical value of the normalization constant A for k=5.55 1/nm and w =7.19 1/ps?

Homework Equations

intergral Y^2=1

The Attempt at a Solution

I tried setting x=0 so my equation becomes Y(0,t)= A*e^-iwt
I then squared the equation A^2*intergral of e^2(-iwt)

I don't know where to go from here can someone help?

More correctly, it's integral of Y times complex conjugate Y. So the time dependence drops out. The remaining x integral is not that challenging, is it?
