Foundational Physics: Light, Electricity, and Magnetism

Do you need a solid understanding of the fundamental forces that shape our technological world? Grasping the basics of light, electric currents, and magnetism is essential for success in science and engineering fields. This course provides a complete text-based introduction to foundational physics, enabling you to confidently analyze simple optical systems and solve common circuit problems using established physical laws. ### What you'll learn * Understand the laws of reflection and refraction, and apply ray diagrams to predict image formation by mirrors and lenses. * Analyze the structure and function of the human eye and describe common vision defects like myopia and hyperopia. * Master the core concepts of electric current, potential difference, resistance, and calculate power consumption in series and parallel circuits. * Apply Ohm's Law and the principles of electrical energy to practical problems, including calculating efficiency and load requirements. * Learn the relationship between electricity and magnetism, identifying magnetic fields generated by currents and understanding basic electromagnetic induction. The course begins with defining key terminology and standard units before moving into the principles of optics and vision. We then transition into detailed coverage of electrical circuits and conclude with the foundational concepts of magnetism and electromagnetism, focusing on rigorous written explanations and practical calculation methods. This course is designed specifically for absolute beginners or those needing a thorough refresher in introductory physics; no prior knowledge is required.
