Light and sound are two forms of energy that allow us to see and hear. Light travels much faster than sound and moves in straight lines. Sound is produced by vibrations and travels through different media. Both light and sound can be reflected, and their properties are useful in many applications. Learning about light and sound helps us understand phenomena like echoes, mirrors, lenses, and musical instruments.
