Essential College Physics Volume II effectively introduces students to critical concepts in physics in an approachable and innovative way. Throughout the text, students enjoy clear and concise explanations, relevant real-world examples, and problems that help them master physics fundamentals. The text begins with six chapters on electricity and magnetism, culminating with a concluding chapter on electromagnetic waves and relativity. Following this are two chapters on optics - one on geometrical optics and another on wave optics. The final four chapters cover modern physics, including quanta, atoms, nuclei, and elementary particles. Each chapter features annotated figures and detailed problem-solving strategies to help students learn and retain the material with confidence. The second edition includes a new four-color format, with color coding of pedagogical features to call greater attention to each. Additionally, new applications have been added to make select topics more current and engaging, both throughout the text and, when possible, within problem sets. Essential College Physics Volume II is part of a two-volume set. It can be used independently or in tandem with Volume I. When combined, the two texts cover a full-year course in algebra-based physics, divided either into two semesters or three quarters.
