NCERT Class 11 Physics – Waves
The chapter Waves in NCERT Class 11 Physics explores the propagation of disturbances through a medium. It introduces mechanical waves, which require a material medium to travel, and distinguishes between transverse and longitudinal waves based on particle motion relative to wave direction.
Students learn key wave parameters such as wavelength, frequency, time period, and speed of propagation. The chapter explains wave motion equations, superposition principle, and interference of waves. Concepts like standing waves, nodes and antinodes, and energy transport in waves are also covered.
Applications such as sound waves, musical instruments, and seismic waves are discussed to connect theory with real-life phenomena. By practicing NCERT examples and exercises, students strengthen analytical skills, understand wave behavior, and prepare effectively for board exams, JEE, and NEET. Waves form the foundation for advanced topics in optics, acoustics, and modern physics.
