Detailed explanation-1: -While sound moves at a much faster speed in the water than in air, the distance that sound waves travel is primarily dependent upon ocean temperature and pressure.
Detailed explanation-2: -Sound is a wave created by vibrations. These vibrations create areas of more and less densely packed particles. So sound needs a medium to travel, such as air, water-or even solids. Sound waves travel faster in denser substances because neighboring particles will more easily bump into one another.
Detailed explanation-3: -In water sounds travels faster than the air. The reason is that the particles are much closer in water and so they can quickly transmit vibration energy from one particle to next particle.
Detailed explanation-4: -In which medium sound travels faster: air or iron? Answer: The speed of sound is faster in solid as compared to gas. Thus, the speed of sound is more in iron.
Detailed explanation-5: -Sound can travel through solids and liquids, but not through gases.
