![]() The table below lists the speed of sound in various media. The speed of sound in solid is 6000 metres per second, while the speed of sound in steel is equal to 5100 metres per second. What is the speed of sound through air - 25840582.So, speed of sound in liquids lies in between the speed of sound in solids and gases. Sound moves incredibly fast You snap your fingers, and it can be heard almost instantly throughout an entire room. The speed of sound in a medium depends on the mediums modulus of elasticity ( E) and its density () according to the relationship c ( E /). In air at 20☌ sound travels at 344 m s 1, in water at 20☌ it travels at 1461 m s 1, and in steel at 20☌ at 5000 m s 1. Therefore the distances between molecules is more in liquids than in solids but is less than in gases. The speed at which sound waves are propagated through a material medium. The difference between those times is 332 ms 0.322 s. Using microphones and data logger A data logger can measure and record the time taken for sound to reach two microphones. He will hear the sound through the rod in x/v seconds where v is the speed of sound in aluminum. Speed of sound in liquid lie in between the speed of sound in solids and gases: Liquid is more dense than gas but less dense than solid. The speed of sound in air is 340 m/s so if the rod has length x, in meters, the man will hear the sound through the air in x/240 seconds.It takes less effective time for a molecule of a solid to bump into its neighbouring molecule and thus, the speed of sound in a solid is larger than in gas. A Mach number is derived by comparing the speed of an airplane with the speed of sound in the air its moving through. Due to this, they can collide very quickly. So, the molecules are closer to each other in solids than in liquids and gases. This is consistent with the general relationship for sound speed in gases since the density of helium is so much less than that of air. As a plane flies, the noise of its engines spreads out as sound. ![]() Speed of sound in a solid is larger than in gas: Solids are significantly denser than liquids or gases. The speed of sound in helium at 0☌ is about 972 m/s, compared to 331 m/s in air. Sound waves travel through air at about 740mph (1,200km/h), or slower at higher altitudes.It varies by a small amount (a few percent) from place to place, season to season, morning to evening, and with water depth. The speed of sound in seawater is not a constant value. Sound travels much more slowly in air, at about 340 meters per second. Since gases expand to fill the given space, density is quite uniform irrespective of the type of gas, unlike solids and liquids. How fast is the speed of sound underwater Sound travels about 1500 meters per second in seawater. ![]() ![]()
