Laser light is incident upon a double slit. The double slit is oriented vertically. The interference pattern is observed on a screen at a distance of 1.63 m away from the slit. The intensity of the light is measured with an electronic sensor in the plane of the screen along the horizontal axis. Please, see figure. Intensity (relative unit) x (mm) If the wavelength of the laser light is 547.0 nm, then what is the slit separation?

1. Consider the rate equation for the probability amplitude: \[ \dot{c}_{n}=(i \hbar)^{-1} \sum_{k} \lambda H_{n k}^{\prime}(t) c_{k}(t) \exp \left(i \omega_{n k} t\right) \] For the case of weak interaction Hamiltonian, we can expand $ c_{n}(l) $ in orders of the perturbation parameter $ \lambda $. Find out the equations at each order of $ \lambda $ as obtained in the lectures.

Question 5 (20 marks) Determine the Fourier transform of $f(t) = \frac{\sin^2 3t}{t}$. 6) $P[t] = \frac{\sin^2 3t}{t} = t \frac{\sin^2 3t}{t^2} = t(\frac{\sin(\frac{3\pi t}{\pi})}{\frac{3\pi t}{\pi}})^2 = 9t \frac{\sin^2 \frac{3\pi t}{\pi}}{[\pi \frac{3}{\pi} t]^2}$ $= 9t \text{Sinc}^2(\frac{3}{\pi}t) = 9t \text{Sinc}^2(\frac{12t}{4\pi})$ $\text{Sinc}^2(\frac{12t}{4\pi}) \iff \frac{2}{12} \times 2\pi (1 - \frac{2|\omega|}{12})P_{12}(\omega)$ $t \times x[t] \iff j\frac{d}{d\omega}X(\omega)$ $\int[P_{12}(t)] = \frac{j\pi}{3}\frac{d}{d\omega}[(1 - \frac{|\omega|}{6})P_{12}(\omega)] = \frac{j\pi}{3}[0 - \frac{\omega}{|\omega|}\frac{1}{6}P_{12}(\omega)]$ $= -\frac{j\pi}{18}(\frac{\omega}{|\omega|}P_{12}(\omega))$
