Foundations of Physics: Waves, Sound, and Light

Waves are all around us, from the music we hear to the light that allows us to see the world. Understanding how these phenomena work is essential for mastering introductory physics and grasping how modern technology functions. This text-based course guides you through the core concepts of wave physics, sound, and light. By reading clear breakdowns and working through step-by-step written exercises, you will develop a strong mental model of how energy travels through space and matter. What you'll learn: - Understand the fundamental properties of waves, including amplitude, wavelength, frequency, and speed. - Differentiate between transverse and longitudinal waves using real-world examples. - Analyze the behavior of sound waves, including pitch, loudness, and the Doppler effect. - Explore the electromagnetic spectrum, focusing on visible light, reflection, refraction, and diffraction. - Apply mathematical wave equations to solve introductory physics problems. - Examine modern applications of wave theory, such as fiber optics and wireless communication. The course starts with essential terminology and the basic physics of mechanical waves before progressing to the specific behaviors of sound and light. You will progress from core theory to practical problem-solving through structured reading and self-assessment questions. This course is designed for high school students, introductory college learners, or anyone curious about physics, with no prior advanced mathematics or science background required.
