This course explores the fundamental principles governing oscillations, waves, and light, providing a unified understanding of these ubiquitous physical phenomena. We begin with simple harmonic motion (SHM), analyzing systems like mass-spring oscillators and pendulums. Building upon SHM, we investigate mechanical waves, covering key concepts such as transverse and longitudinal waves, superposition, interference, and standing waves on strings and in air columns. The course then transitions to the study of electromagnetic waves, identifying light as a primary example. This leads into Geometrical Optics, where we apply the ray model to understand reflection and refraction using mirrors and lenses. We will thoroughly analyze the formation of images by various optical instruments. The final section delves into Physical Optics, which treats light as a wave, focusing on diffraction and interference phenomena like Young's Double-Slit experiment and diffraction gratings. The mathematical framework, including differential equations and complex numbers, will be used to describe the underlying physics. By the end of the course, students will be able to analyze and solve problems involving oscillating systems, wave behavior, and the manipulation of light.
