The proportional variation of speed with density is clearly visible here.Another very curious fact is that in solids, sound waves can be created either by compression or by tearing of the solid also known as Shearing. Earthquakes are created due to the movement of the earth plates which then sends these disturbances in the form of waves similar to sound waves through the earth and to the surface causing an Earthquake.

The speed of sound in gases is proportional to the square root of the absolute temperature (measured in Kelvin) but it is independent of the frequency of the sound wave or the pressure and the density of the medium. Therefore, the speed of sound decreases as the density of the medium increases.The temperature of the medium and the sound waves are directly proportional to each other. In the olden days, doctors used stethoscopes consisting of thin wooden rods with broadened ends and they worked exactly like our modern ones and performed just as well. The speed of sound through air is 346 m/s at 25 °C. This means that the molecules are closer to each other in solids than in liquids and in liquids than in gases. Although sound travels quite fast, it is still possible to measure its speed in air. Speed of sound is used for describing the speed of sound waves in an elastic medium.The formula for speed of sound is given with respect to gases. It is the square root of the product of the coefficient of There are two factors that affect the speed of sound:For sound waves to travel, there is a requirement of medium and density of the medium is considered to be one of the factors on which the speed of sound depends. In seismic terms, the compression waves are called P-waves and the tearing waves are called Pitch is the property which is used for distinguishing a sharp sound from a dull sound.
The high speed of sound is responsible for the amusing "Donald Duck" voice which occurs when someone has breathed in helium from a balloon. In particular, for dry air at a temperature of 0 °C (32 °F), the modern value for the speed of sound is 331.29 metres (1,086.9 feet) per second. Speed of sound, speed at which sound waves propagate through different materials. Speed of sound. To convert between Speed Of Sound [air] and Centimeter/second you have to do the following: First divide 340.29 / 0.01 = 34029. SPEED OF SOUND [AIR] TO CENTIMETER/SECOND (c TO cm/s) CHART .
To do this, you need to measure the time it takes a sound to travel a measured distance. Sound travels slower in air in comparison with its travel in liquids and solids. Sound waves travel through a medium by alternately contracting and expanding the parts of the medium in which it travels. This closeness due to density means that they can collide very quickly. Hence the speed of sound in liquids lies in between the speed of sound in solids and gases.The speed of sound in water is more than that of the air. The speed of sound in air is approximately figured out by the formula …For example, the speed of sound in air is 386 m/s at 100 °C. The speed of sound is dependent on the medium through which the waves of sound travel. Sound surrounds us everyday. The properties that have an affect on the speed of sound in air are pressure, density, and molecular mass of the medium.The lower the density that of a medium, the faster the speed of sound and the higher the compressibility is, the slower the sound travels. Therefore the distances between molecules are more in liquids than in solids but are less than in gases. Higher the frequency, the higher the pitch.The intensity of sound is defined as the amount of energy passing through the unit area at that point. Calculator Ideas. The speed of sound in air is approximately 331.5 m/s at 0 °C or around 1200 km per hour.
