Query: Good for practice and review

I utilized this workbook almost solely for the practice problems and concept review before optics exams. I appreciated the practice problems and the answer key because the best way to understand this information and memorize the equation is to work the problems. Be careful to check for errors, as there are some equations written incorrectly. With that said, this is a good supplementary workbook but should not be the only source used.
