e. The speed of sound is the distance travelled per unit of time by a sound wave as it propagates through an elastic medium. More simply, the speed of sound is how fast vibrations travel. At 20 °C (68 °F), the speed of sound in air is about 343 m/s (1,125 ft/s; 1,235 km/h; 767 mph; 667 kn), or 1 km in 2.91 s or one mile in 4.69 s.
Speed of Sound (song) " Speed of Sound " is a song by British rock band Coldplay. It was written by all members of the band for their third studio album, X&Y (2005). Constructed around a piano and guitar riff, the song builds into a huge, synthesiser-heavy chorus. It was released by Parlophone Records as the lead single from the album.
The speed of sound depends on the medium the waves pass through, and is a fundamental property of the material. The first significant effort towards measurement of the speed of sound was made by Isaac Newton. He believed the speed of sound in a particular substance was equal to the square root of the pressure acting on it divided by its density:
Released: 28 June 1976. Wings at the Speed of Sound is the fifth studio album by the British–American rock band Wings, released on 26 March 1976. [1] Issued at the height of the band's popularity, it reached the top spot on the US album chart—the band's fourth consecutive album to do so—and peaked at number 2 on the UK album chart.
The Mach number (M or Ma), often only Mach, (/ mɑːk /; German: [max]) is a dimensionless quantity in fluid dynamics representing the ratio of flow velocity past a boundary to the local speed of sound. [1][2] It is named after the Austrian physicist and philosopher Ernst Mach. where: M is the local Mach number, u is the local flow velocity ...
Speeds of sound of the elements. The speed of sound in any chemical element in the fluid phase has one temperature-dependent value. In the solid phase, different types of sound wave may be propagated, each with its own speed: among these types of wave are longitudinal (as in fluids), transversal, and (along a surface or plate) extensional.

The Speed of Sound is a 1988 all-instrumental album by American rock guitarist Ronnie Montrose, who led the bands Montrose (1973-77 & 1987) and Gamma (1979-83 & 2000) and also performed and did session work with a variety of musicians, including Van Morrison (1971–72), Herbie Hancock (1971), Beaver & Krause (1971), Boz Scaggs (1971), Edgar Winter (1972 & 1996), Gary Wright (1975), The Beau ...
The sound source is travelling at 1.4 times the speed of sound (Mach 1.4). Since the source is moving faster than the sound waves it creates, it leads the advancing wavefront. A sonic boom produced by an aircraft moving at M=2.92, calculated from the cone angle of 20 degrees.
