PHY 119/ENS 119 is a course in the principles of physics as they apply to environmental issues. A review of mathematics is followed by a discussion of Newton's laws, conservation principles, topics in fluids and wave motion, optical instruments, and radioactivity. Three lectures and one laboratory session per week.

PHY 119 and ENS 119 are typically offered in Spring semester. Please see SBU Solar or Brightspace for more information.

Here is a (partial) archive of lab manuals used in PHY 119.

These are here for background information only. Please follow guidance from your instructor as to what materials to use and what procedures to follow in your course.
