The given circuit can be rearranged as
Now the equivalent capacitance of two 1 µF capacitors in parallel is given by
In a Young's double slit experiment, three polarizers are kept as shown in the figure. The transmission axes of and are orthogonal to each other. The polarizer covers both the slits with its transmission axis at to those of and . An unpolarized light of wavelength and intensity is incident on and . The intensity at a point after , where the path difference between the light waves from and is , is:
