Jenny Magnes, Professor of Physics, and Juan Merlo-Ramírez, Associate Professor of Physics, recently published a new book, Optical Interference and Dynamic Diffraction: Research methods for undergraduates. Their book introduces Dynamic Optical Diffraction (DOD), developed by Professor Magnes, and draws on both authors’ pedagogical experience to “fill in the elementary material often omitted from the literature on diffraction and Fourier transforms,” mathematical tools that help analyze signal frequencies.
