Why is the speed of sound more in sea water than distilled water?
As sound wave is propagated due to vibration of particles, closer the particles / denser the particles faster the speed of sound. Since, density of sea water is more than distilled water due to the presence of salt in it speed of sound is more in seawater than distilled walter.
Why does sound travel faster in seawater than in air?
In water, the particles are much closer together, and they can quickly transmit vibration energy from one particle to the next. This means that the sound wave travels over four times faster than it would in air, but it takes a lot of energy to start the vibration.
How is distilled water different from sea water?
Seawater is a mixture of many different substances. In distilled water all of the dissolved substances mixed in water have been removed by evaporation. As water evaporates, it distills, or leaves the salt behind. The pure evaporated water is collected and condensed to form distilled water.
How does the speed of sound in sea water compare to the speed of sound in air?
The speed of sound in sea water is, on average, about 1560 m/s, or 3490 mph. Compare this to the speed of sound in air, which is 343.2 m/s. The discrepancy is obvious: sound travels nearly five times faster in seawater than in dry air!
What is the speed of sound in sea water?
In the oceans the speed of sound varies between 1,450 and 1,570 metres (about 4,760 to 5,150 feet) per second. It increases about 4.5 metres (about 15 feet) per second per each 1 °C increase in temperature and 1.3 metres (about 4 feet) per second per each 1 psu increase in salinity.
Does sound travel faster or slower in air compared with water?
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. This causes the speed of sound to increase and makes the sound waves refract upward.
