How much faster does sound travell underwater?

Answer 1

The sound through water travels 300 miles per hour (INCORRECT)

It travels at about 10 times that speed in water - closer to 3000 miles per hour, although the purity of the water, the temperature and the pressure will also affect the speed.

Answer 2

Sound travels more than 4 times faster in water than it does in air, specifically about 1484 meters per second.
In fresh water, sound travels at about 1497 m/s (3,348 mi/hr) at 25 °C (77 °F). At 0 °C (32 °F - the freezing point of water) it is about 1402 m/s (3,136 mi/hr). At 100 °C (212 °F - the boiling point of water at atmospheric pressure) it is about 1543 m/s (3,451 mi/hr) Note: all these values are for fresh water at atmospheric pressure

In salt water that is free of air bubbles or suspended sediment, sound travels at about 1560 m/s - but this is only an average. The actual speed depends on the salinity of the water (which changes quite a bit as you move away from the coast, and/or change in depth), on temperature (which varies enormously as you move from one pole, through the equator, and down to the other pole - as well as from season to season and with depth), and pressure (which, of course changes a lot with depth). Higher salinity increases the speed - by around 0.25% on average. Pressure increase the speed by up to 12% in the deepest part of the ocean. Temperature can change the speed by about 10% from 0 °C to 100 °C. The coldest recorded ocean water was around -3 °C for a subsurface stream in Antarctica. The hottest ocean water is probably near hydrothermal vents on the ocean floor where it can reach around 464 °C - although in this case, the water is actually a supercritical fluid and will not behave like normal liquid.

The speed of sound in a supercritical fluid is rather counterintuitive due to the high density, low viscosity, and high compressibility of supercritical fluids. Near the critical point, the speed of sound can drop precipitously since the pressure waves that constitute the transmission of sound cause extremely large changes in the densities of the near-critical fluid.

Answer 3

Since sound requires medium to travel(thats why we don't hear nuclear booms from sun),

so denser the medium, higher is the velocity of sound.

speed of sound in air=330m/s

speed of sound in water=1500m/s

speed of sound is solid=5000m/s

so sound travels about 5 and 16.67 times faster in water and solid medium respectively

Answer 4

sound travels at a speed of 0.62 miles per second.

More like 1500 meters per second. Its pretty fast and or 3,348 mph

Answer 5

In fresh water @ 20 degrees C = 1482 metres per second (3315 mph)

Answer 6

It travels approxamately 660 mph or miles per hour it also depends on depth though. F

Answer 7

about 1500 meters per second
