Sound and light are both forms of energy, but they differ in several ways:
1. Medium: Sound waves require a medium, such as air or water, to travel through, while light waves can travel through a vacuum like space.
2. Speed: Sound waves travel at a much slower speed than light waves. The speed of sound is around 343 meters per second in air, while the speed of light is around 299,792,458 meters per second.
3. Direction: Sound waves travel in all directions from their source, while light waves generally travel in straight lines unless they are refracted or reflected.
4. Wavelength: The wavelength of sound waves is much longer than that of light waves. The range of audible sound waves for humans is between 20 Hz and 20,000 Hz, while the range of visible light waves is between 400 and 700 nanometers.
5. Interaction with matter: Sound waves can be absorbed, reflected, or transmitted by different materials, while light waves can be absorbed, reflected, refracted, and diffracted by matter.
6. Perception: Sound is detected by the ear and perceived as a sensation of hearing, while light is detected by the eye and perceived as a sensation of seeing.
