(waves class) please answer the questions in the following order: 1. if you were shown three different interference patterns (double slit, single slit, and diffraction grating), how could you tell the difference between them? 2. Newton thought that light wasnt a wave because he couldn’t see diffraction or interference. Imagine you are transported back in time to convince him otherwise. Write a 1-2 paragraph explanation for Newton explaining why he does not see these features despite the wave of natural...
