Chapter 15 – Waves
Chapter 15 – Waves explains the propagation of disturbances through a medium without the transfer of matter. It introduces different types of waves such as transverse waves and longitudinal waves, along with key terms like wavelength, frequency, amplitude, time period, and wave speed.
The chapter also discusses sound waves, their characteristics, and the mathematical relationship between wave speed, frequency, and wavelength. Concepts such as superposition of waves, reflection of sound, and Doppler effect (basic idea) are introduced. This chapter is highly important for CBSE board exams and competitive exams like NEET and JEE.
