College Physics II

Exam Preparation Guide

Course Introduction

College Physics II is a continuation of the foundational concepts introduced in College Physics I, focusing on electromagnetism, optics, and modern physics. Topics typically include electric forces and fields, electric potential, circuits, magnetism, electromagnetic induction, light and optical phenomena, and an introduction to quantum and nuclear physics. Emphasis is placed on developing problem-solving skills through the application of physical principles to real-world scenarios, with laboratory exercises complementing theoretical learning and reinforcing core concepts. This course is designed for students pursuing studies in the life sciences, health professions, and other fields that require a comprehensive understanding of basic physics principles.
