What factors affect the speed of sound?
The speed of the sound depends on the density and the elasticity of the medium through which it travels. In general, sound travels faster in liquids than in gases and quicker in solids than in liquids. The greater the elasticity and the lower the density, the faster sound travels in a medium.
How does the salinity of water affect the speed of sound?
The speed of sound is not constant throughout the ocean, but varies with differences in water temperature, pressure, and salinity. The speed of sound increases with increasing temperature, pressure, or salinity. The speed of sound decreases as temperature, pressure, or salinity (increases) (decreases).
Does water pressure affect the speed of sound?
There is a minimum in sound speed at a depth of roughly 1000 m in mid-latitudes. Sound speed near the surface decreases with increasing depth due to decreasing temperature. The sound speed at the surface is fast because the ocean is warmed by the sun heating the upper layers of the ocean.
What effect the speed of sound as it travels?
The speed varies depending on atmospheric conditions; the most important factor is the temperature. Humidity has little effect on the speed of sound, nor does air pressure by itself. Sound usually travels more slowly with greater altitude, due to reduced temperature.
What is the speed of sound waves in liquids?
1,482 meters per second
Sound travels faster in liquids than in gases because molecules are more tightly packed. In fresh water, sound waves travel at 1,482 meters per second (about 3,315 mph). That’s well over 4 times faster than in air!
How does water affect the speed of sound?
The speed of sound waves depends on the medium used, not on the number of vibrations. Sound travels faster in solids and liquids, and slower in gases. The speed of sound in pure water is 1,498 meters per second, compared to 343 meters per second in air at room temperature and pressure.
What happens to sound waves as they travel through the ocean?
As the whale’s sound waves travel through the water, their speed decreases with increasing depth (as the temperature drops), causing the sound waves to refract downward. Once the sound waves reach the bottom…
How does sound in air differ from sound in water?
How does sound in air differ from sound in water? Sound in water and sound in air are both waves that move similarly and can be characterized the same way. Sound waves can travel through any substance, including gases (such as air), liquids (such as water), and solids (such as the seafloor).
How much slower does sound travel in air than in seawater?
Sound travels about 1500 meters per second in seawater. Sound travels much more slowly in air, at about 340 meters per second. The speed of sound in seawater is not a constant value.
