This chapter explains the concept of waves and energy, highlighting how waves transport energy without transporting matter. It covers mechanical waves (sound, water, seismic) and electromagnetic waves (light, radio, microwaves). Examples include sound waves from an alarm, water ripples, and the tuning fork experiment, which demonstrates how sound waves travel through air. The content helps students understand wave propagation, vibrations, and the difference between mechanical and electromagnetic waves in physics.
