The second course in an three-quarter algebra-based sequence. A balance of conceptual understanding and problem-solving ability is emphasized; laboratory and lecture are integrated in the sequence. In this second quarter the topics studied will include fluids, oscillations, waves and sound, thermodynamics, geometric and physical optics. Biological applications of physics will be studied whenever possible.

### Prerequisites

Completion of PHYS& 114 with 2.0 or higher.

Upon successful completion of the course, students should be able to demonstrate the following knowledge or skills:

- Apply algebra and right-angle trigonometry to the solution of problems involving fluids, oscillations, waves, sound, thermodynamics, geometric and physical optics.
- Apply conceptual reasoning to analyze situations involving the material studied in this course.
- Present well-reasoned solutions of problems.
- Present experimental results in clearly written laboratory reports.
- Use technology such as calculators and computer spreadsheets to perform calculations, analyze data, and present data in graphical form at levels appropriate for the course.
