The video explores how light and sound waves behave, covering key concepts such as reflection, transmission, absorption, refraction, diffraction, and scattering. Reflection involves waves bouncing off surfaces, while transmission sees them passing through objects. Absorption and reflection determine an object's color, and refraction changes wave direction at boundaries. Diffraction occurs when waves pass through gaps, and scattering explains phenomena like the blue sky.
