Description and Objectives:

This course provides students an insight of the principles of waves as carriers of energy including sound and optical waves mainly. This course also provides the students with a broad understanding of the physical principles of the oscillations, to help them develop critical thinking and quantitative reasoning skills, to empower them to think creatively and critically about scientific problems and experiments.
