In a double-slit interference pattern, it is the amplitudes of the light waves from each slit that add, not the light intensities. Usually, in the analysis of interference patterns, the radiation intensity (or amplitude) is assumed to be exactly the same for both slits. Because of inaccurate optical alignment, however, the illumination is often not the same for the two slits. If the intensity of light going through one slit is \(0.010 \mathrm{~mW} / \mathrm{mm}^{2}\) while the intensity going through the second slit is \(0.030 \mathrm{~mW} / \mathrm{mm}^{2}\), what is the intensity at an interference maximum and at an interference minimum?
