(a) An object comprises a periodic sinusoidal amplitude transmittance $t(x) = 1 + m \cos Kx$, $m < 1$ with a spatial frequency $K = 2\pi \times 100 \, rad/mm$. The object is illuminated by a plane wave of wavelength 1 micron traveling along the optical axis (z-axis). (i) Assuming Fresnel propagation only, find the nearest self-imaging (or Talbot imaging) distance. (ii) Again, assuming Fresnel propagation only, find the nearest distance where there will be contrast reversal.

The circuit has been as shown in the figure for a long time. $L_1$ is the inductor on the top left, $L_2$ is the inductor on the bottom left, $L_3$ is the inductor on the bottom right. The voltage source is $V_s = 6$ volts, and the current source is $I_s = 4$ amps. The switches have been as shown for a long time. At $t = 0$, $sw_1$ opens and $sw_2$ and $sw_3$ close. Determine the current and voltage in every inductor and in the capacitor right after $t = 0$, that is at $t = 0^+$. Currents are considered positive as follows: $L_1$, left to right, all other inductors, top to bottom. Voltage convention for the capacitor is positive at the top, and remember, in passive elements, \"water falls from the sky\".
