Sound travels slower than light
Sound: Mechanical and Longitudinal Light: Electromagnetic and Transverse Sound: Mechanical and Longitudinal Speed: 340 m/s 770 mph Speed: 300,000,000 m/s 670,000,000 mph
Sound travels faster/slower, depending on the medium Liquids are not packed as tightly as solids. And gases are very loosely packed. The spacing of the molecules enables sound to travel much faster through a solid than a gas. Sound travels about four times faster and farther in water than it does in air.
