WebSound moves at a faster speed in water (1500 meters/sec) than in air (about 340 meters/sec) because the mechanical properties of water differ from air. Temperature also affects the speed of sound (e.g. sound travels faster in warm water than in cold water) and is very influential in some parts of the ocean. WebMoving Light. Light from a moving source also travels at 300,000 km/sec (186,000 miles/sec).
