If you're struggling with the math in Chapter 7 (Superposition) or Chapter 10 (Diffraction), double-check your understanding of complex numbers and Euler's Formula . Most of Hecht's solutions rely heavily on these mathematical shortcuts.
It is tempting to use a solution manual to finish homework quickly, but in a subject as cumulative as optics, "shortcut" learning usually fails during exams. optics hecht 5th edition solution manual
