WebApr 29, 2024 · In this activity, students make sense of and use real world data to investigate a variety of phenomena including the speed of sound, waves, air pressure, humidity, and temperature at high altitude. Using data collected with payload sensors attached to a high-altitude balloon students examine, interpret, verify theoretical speed of sound equations. WebOct 16, 2015 · Typically, sound can travel through room temperature air (about 68 degrees Fahrenheit) at 344 meters per second. When the air drops to freezing temperatures, however, the speed of sound drops to 331.5 meters per second. This is because sound waves need mediums like air, water or solids to carry them. When heat is added to the … diversity atlas
How Does Temperature Affect the Speed of Sound? - Reference.com
The speed of sound is the distance travelled per unit of time by a sound wave as it propagates through an elastic medium. At 20 °C (68 °F), the speed of sound in air is about 343 metres per second (1,125 ft/s; 1,235 km/h; 767 mph; 667 kn), or one kilometre in 2.91 s or one mile in 4.69 s. It depends strongly on … See more Sir Isaac Newton's 1687 Principia includes a computation of the speed of sound in air as 979 feet per second (298 m/s). This is too low by about 15%. The discrepancy is due primarily to neglecting the (then unknown) effect of … See more The transmission of sound can be illustrated by using a model consisting of an array of spherical objects interconnected by … See more The speed of sound is variable and depends on the properties of the substance through which the wave is travelling. In solids, the speed of transverse (or shear) waves depends on the shear deformation under shear stress (called the See more General physical considerations The medium in which a sound wave is travelling does not always respond adiabatically, and as a result, the speed of sound can vary … See more The speed of sound in mathematical notation is conventionally represented by c, from the Latin celeritas meaning "velocity". See more In the Earth's atmosphere, the chief factor affecting the speed of sound is the temperature. For a given ideal gas with constant heat … See more Speed of sound in ideal gases and air For an ideal gas, K (the bulk modulus in equations above, equivalent to C, the coefficient of stiffness in solids) is given by See more WebMar 27, 2016 · The same effect also affects the pressure field around an aircraft which is moving close to the speed of sound. Its movement displaces air and has an effect similar to a contracting duct, accelerating the flow in its vicinity as long as the aircraft grows thicker in flow direction, and decelerating it again over its rear half where it contracts. WebFeb 19, 2015 · 12. I read once that Mach speed decreases as altitude increases. The speed of sound is solely dependant on temperature.
