The speed of sound is influenced by several factors, including medium, density and temperature. The rate at which sound waves moves varies widely from one situation to the next and can change dramatically in a short period of time.Know More
Sound waves are considered to be longitudinal waves, which means that particles in the air surrounding these waves move in parallel motion to the waves. An example is the movement of a guitar string, which moves rapidly from side to side when plucked. In a neutral or unmoving state, the guitar string is surrounded by an equal number of air particles on all sides. Like a rock, leaf or insect that penetrates the surface of a placid lake or pond, however, the creation of movement in the guitar string disturbs the surrounding air particles and creates movement. When stimulated by the string, particles may move closer together or farther apart.
The substance through which sound travels is called the medium, and sound moves best through air and water. The density of the medium affects the speed of sound. In the case of air, humidity, density, temperature, and moisture can affect air density and in turn affect the speed of sound. On a muggy day, for example, sound travels slower because humidity makes the air more dense.Learn more about Motion & Mechanics
The speed of sound, known as Mach 1, varies depending on the medium through which a sound wave propagates. In dry, sea level air that is around 25 degrees Celsius, Mach 1 is equal to 340.29 meters per second, or 1,122.96 feet per second.Full Answer >
The speed of sound is dependent on the medium through which it is traveling. Under typical conditions, at sea level, sound travels 1,225 kilometers per hour, or 340.29 meters per second.Full Answer >
In aeronautics, the Mach number M is the ratio between the speed of an object moving through a medium and the speed of sound of that medium. Mach 1 represents the speed of sound in air, which is approximately 330 meters per second, or 760 miles per hour.Full Answer >
Sound travels in waves from a transmitter to a receiver through a medium. The wave is produced by the vibration of particles in mediums such as gases, liquids and solids. Because sound requires a medium of interconnected and interactive particles, it cannot travel in a vacuum such as space.Full Answer >
