Wave and Optics – Complete Topic List
A. Wave Basics
In this section, we will discuss the fundamental ideas of Wave Basics, starting with the definition of a wave and how it behaves in different mediums. We will explore the two major types of waves—mechanical and electromagnetic—and understand the differences between transverse and longitudinal waves. The key wave parameters such as wavelength, frequency, amplitude, and period will also be explained, along with the formula for wave speed. Finally, we will look into the concepts of phase, phase difference, and the superposition principle to understand how waves interact with one another.
B. Wave Behaviors
In this section, we will explore Wave Behaviors, examining how waves respond when they encounter different obstacles and mediums. We will discuss the reflection of waves and how they bounce back, followed by refraction, where waves change direction as they move between mediums. The concept of diffraction will show how waves bend around edges, while interference will explain how waves combine to produce constructive or destructive patterns. We will also study standing waves and understand how they form, along with the phenomenon of beats and beat frequency. Finally, we will look into the Doppler effect to see how the observed frequency of a wave changes due to relative motion between the source and the observer.
C. Optics (Geometrical Optics)
In this section, we will focus on Geometrical Optics, beginning with the rectilinear propagation of light, which explains how light travels in straight lines. We will study the reflection of light and understand image formation in plane mirrors, followed by a detailed look at spherical mirrors—both concave and convex—and how they produce different types of images. The mirror formula and magnification will also be discussed to analyze object-image relationships. Moving to refraction, we will cover Snell’s law, refractive index, and optical density to explain how light bends when entering different mediums. We will then explore total internal reflection and its applications. The section also includes the behavior of light through lenses, both convex and concave, along with the lens formula and magnification. Finally, we will examine how prisms deviate light and how dispersion creates the visible spectrum.
D. Physical Optics
In this section, we will explore Physical Optics, starting with Huygens’ Principle, which provides a wave-based explanation of how light propagates. We will discuss Young’s double-slit experiment (YDSE) and how it demonstrates the interference of light, followed by interference produced through the division of wavefront and the colorful patterns seen in thin films such as soap bubbles. The concept of diffraction will be examined through single-slit and double-slit setups to understand how light bends and spreads around openings. We will also study the resolving power of optical instruments and how diffraction limits their ability to distinguish fine details. Additionally, this section covers the polarization of light, explaining how the orientation of light waves can be controlled. Finally, we will learn about Brewster’s angle and Malus’ law, which describe important principles related to polarized light.
