HC Verma Vol-1 Chapter-17 Solutions: Light Waves
Chapter 17 of HC Verma’s Concepts of Physics Vol-1, titled “Light Waves,” explores the fascinating and fundamental behavior of light as a wave. This chapter plays a crucial role in understanding interference, diffraction, polarization, and the wave theory of light — key topics for students preparing for JEE Main, JEE Advanced, NEET, and other engineering or medical entrance exams.
In this write-up, we provide complete, step-by-step solutions to all the questions in HC Verma Chapter 17. These solutions are crafted to help students build clarity, precision, and a deeper understanding of light’s wave nature and associated concepts.
Overview of Chapter 17: Light Waves
This chapter introduces students to:
-
The wave theory of light
-
Nature of electromagnetic waves
-
Superposition principle
-
Interference of light (Young’s Double Slit Experiment)
-
Diffraction and its effects
-
Polarization and unpolarized light
-
Coherent and incoherent sources
It shifts the focus from ray optics to wave optics and lays the groundwork for later chapters in modern physics and quantum optics.
