Light can travel through a vacuum, allowing it to move through space without needing a medium, whereas sound waves require a medium like air, water, or solid materials to propagate. Additionally, light can be refracted, reflected, and diffracted, enabling phenomena such as rainbows and optical illusions, which sound waves cannot achieve in the same manner. Furthermore, light can exhibit a wide range of frequencies beyond the audible spectrum, including ultraviolet and infrared, which sound cannot.
