Sound waves are mechanical waves that require a medium to travel, while light waves are electromagnetic waves that can travel through a vacuum. Sound waves travel slower than light waves, with speeds of approximately 343 meters per second in air compared to the speed of light at 299,792 kilometers per second in a vacuum. Sound waves transfer energy through the vibration of particles, while light waves transfer energy through the oscillation of electric and magnetic fields. Sound waves are detected by the human hearing range of 20 Hz to 20,000 Hz, while light waves are detected by our eyes within the visible spectrum of approximately 400 to 700 nanometers. Sound waves interact with objects through phenomena like reflection, refraction, and diffraction, while light waves also exhibit characteristics of interference and polarization. In summary, sound waves and light waves have distinct properties and behaviors that differentiate them from each other.
