I'm currently an undergraduate Engineering Physics student. My university offers the following specializations within the program: - Renewable Energy - Biomedical Physics and Acoustics - Optics/Photonics I know this mainly comes down to personal interest, but I'm also interested in the practical side / career opportunities. I plan to go to grad school and then begin a professional career. (I'm probably not looking to go the PhD route, as I will be about 32 when finishing grad school.) I'm personally most interested in Optics or Acoustics. My main thought is that Acoustics may be somewhat limited and the job market a little smaller, while Optics seems to have a wide range of applications. Is this correct? Would be great to hear from anyone working in these fields, what types of jobs (and salaries) are most common, and any other info to consider. Thanks!
