What is the speed of sound? in Meters/s?

The speed of sound v in dry air at temperature T (in celsius) is given by:\n\nv = (331.4 + 0.6 T) m/s\n\nSpeed of sound depends on various factors, such as, temperature, humidity, density, etc. of the medium in which it travels.\n \nThe following links provide the speed of sound calculators and related links:

You will find the formula you need just over half way down the page:\n\nhttp://en.wikipedia.org/wiki/Speed_of_sound\n\nI get speed of sound is 4 x faster in oxygen than hydrogen (1/sqrt16)

The speed of light in a vacuum is exactly 299,792,458 metres per second (or 1,079,252,848.8  km·h-1, which is approximately 186,282.397 miles per second, or 670,616,629.4 miles per hour). This value is denoted by the letter c, reputedly from the Latin celeritas, "speed". Note that this speed is a definition, not a measurement, since the fundamental SI unit of distance, the metre, has been defined since 1983 in terms of the speed of light—one metre is the distance light travels in a vacuum in 1/299,792,458 of a second. The speed of light through a transparent medium (that is, not in vacuum) is less than c; the ratio of c to this speed is called the refractive index of the medium.

Frequency (1/second) is speed (meters per second) divided by wavelength (meters).\n\nSpeed is 8.6m / 5s = 1.72 m/s\n\nDivide that by wavelength: 1.72 m/s  / 5m = 0.344 s^(-1)   aka  0.344 Hz.

In metric units, c is exactly 299,792,458 metres per second (1,079,252,848.8 km/h). Note that this speed is a definition, not a measurement, since the fundamental SI unit of length, the metre, has been defined since October 21, 1983 in terms of the speed of light: one metre is the distance light travels in a vacuum in 1/299,792,458 of a second. Converted to imperial units, the speed of light is approximately 186,282.397 miles per second, or 670,616,629.384 miles per hour, or almost one foot per nanosecond.\n\nand everything about speech of light in this site\nhttp://en.wikipedia.org/wiki/Speed_of_light

(m)\n\nThe speed of light in a vacuum is exactly 299,792,458 metres per second (or 1,079,252,848.8  km·h-1, which is approximately 186,282.397 miles per second, or 670,616,629.4 miles per hour). This value is denoted by the letter c, reputedly from the Latin celeritas, "speed", and also known as Einstein's constant. Note that this speed is a definition, not a measurement, since the fundamental SI unit of distance, the metre, has been defined since 1983 in terms of the speed of light—one metre is the distance light travels in a vacuum in 1/299,792,458 of a second. The speed of light through a transparent medium (that is, not in vacuum) is less than c; the ratio of c to this speed is called the refractive index of the medium.

Mach is speed of sound, so M3 is ~2200 mph.\n\nYou could hear your voice because we hear our own vioce partially through internal resonance, which would not be affected by external velocity.

A good approximation is the speed of sound is 331.5 + 0.6 * T.  T is the temperature in Celsius.  The answer is in metres per second.  Using this formula, the speed of sound at 25 degrees Celsius is 346.5 m/s.

The speed of sound in air depends on the temperature of air, and the composition of the air (different amounts of gases or water vapor present ).\nAt 0 degrees Celsius (freezing point), the speed of sound in regular dry atmospheric air is 331.4 meters/second (or 742 miles per hour).\nAt 22 degrees Celsius (71 degrees F), the speed of sound is 344 m/s (772 mph).\nAt 100 degrees C (boiling point), the speed of sound is 392 m/s (878 mph).\nYou can use the link to calculate the speed of sound for any temperature.

sound travels at an avg speed of .78999342 mps or 2843.9763 MPH in seawater depending on water temperature salinity and depth of the source/receiver.\n\nlight averages 186,282 mps or 11,176,920 mph\n\nthe other answers AREN'T WRONG but you should have specified through what medium they are traveling. also you need to specify temperature humidity pressure altitude/depth salinity and or a myriad of other factors\n\nLight has a different speed when passing through our atmosphere than it does through space just as sound through air and water or a solid. the more dense the material the faster the sound transmission. oddly the opposite is true for light.\n\nthis question has been asked several times before.  if you do a search for previous questions you will doubtless find MANY other answers for these very questions with more precise speeds through different mediums.

speed of light = 299,792,458 m/s\nspeed of sound at sea level = 340.29 m/s\nspeed of electricty = probably around 8.4 cm/hour\n\nBut wait...why is electricity so slow?! Light bulb turns on almost instantly! \nAnswers here: http://www.discoverycentermuseum.org/experiments/272.htm

Sound waves are longitudinal waves. They vibrate back and forth in the direction that they aremoving. Sound travels at about 1100 feet /sec.\n\nLight waves are transverse waves, part of the electromagnetic spectrum. they vibrate up and down similar to water waves. They travel at 186,000 miles/sec.

KNOWN:\nf = 3.2 x 10^-2 Hz\nc (ie speed of light) = 3.00 * 10 ^8 m/s\n\nFIND L (AKA wavelength)\nL m = c m/s  /  f Hz\n= 3.00 * 10 ^8 m/s  /  3.2 x 10^-2 Hz\n= 9 375 000 kilometers\n\nAre you sure its 10^-2 Hz? That seems unlikely

The frequency range is generally accepted to be 20 Hz to 20,000 Hz. With the speed of sound = 334 m/s, 20 Hz has a wavelength of 16.7 m, 20,000 Hz a wavelength of 16.7 mm. (Ubergeek, the answerer in your link slipped a decimal place.)
