I'm looking for a good review of Waves before I go into E-Mag, acoustics and vibrations stuff. What would be a solid book for that? I feel like I didn't have a strong foundation in analysing trigonometric functions, and a very weak base using Fourier series, especially with applications. Right now, I'm thinking about A. P. French's Vibrations and Waves, but it seems to only go over only elementary concepts. The normal introductory physics books only seem to give equations and not go into any analytical depth, and I would like to develop some intuition with this type of stuff, especially considering how important waves are. Any better suggestions?
