Homework Statement



In a double-slit experiment, the slits are on the y-axis and the electrons are detected
on a vertical screen. When only slit #1 is open, the amplitude of the wave which
gets through is
\psi(y,t) = A \exp^{-y^2} \exp^{-i((ky-\omega t)}

when only slit #2 is open, the amplitude of the wave which gets through is
\psi(y,t) = A \exp^{-y^2} \exp^{-i(k+\pi)y-\omega t)}

(a) Normalize 1 and 2.


Homework Equations



Normalization Condition
\int_{-\infty}^{\infty}\psi*\psi dy = 1

The Attempt at a Solution




1.
1=\int_{-\infty}^{\infty} A (\exp^{-y^2} \exp^{-i((ky-\omega t)}) (\exp^{-y^2} \exp^{i((ky-\omega t)}) dy <br />
1=A \int_{-\infty}^{\infty} \exp^{-2y^2} dy<br />
<br /> 1/A= \sqrt{\pi/2}<br /> From integral tables

That's the solution i came up with for the first normalisation
Is the second the same?

i think u forgot to put the square over the A

Ha! So i did, thanks.
 
To solve this, I first used the units to work out that a= m* a/m, i.e. t=z/λ. This would allow you to determine the time duration within an interval section by section and then add this to the previous ones to obtain the age of the respective layer. However, this would require a constant thickness per year for each interval. However, since this is most likely not the case, my next consideration was that the age must be the integral of a 1/λ(z) function, which I cannot model.
