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.)

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

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.

The answer depends upon what sort of wave you are talking about and the medium it is travelling. Say for example if it is a light wave through vacuum, then \n\nWavelength = (2.99875 X 10^8) / Frequency.\n\nIf the same is sound through air at 60% humidity and at sea level, then\n\nWavelength = (340) / Frequency.\n\nIf it is a sound wave through water (4 degrees celsius), then\n\nWavelength = (1440) / Frequency.\n\nThe value inside the bracket is the speed of the wave in the respective medium under respective conditions.

First of all, 3 x 10^8 m/s is the speed of light in a vacuum. Thanks for nothing there.\n\nNow, for the speed of sound ...\n\nThe typically cited value is about 340 m/s in standard atmosphere, but the actual speed of sound varies with the medium. \n\nFor an ideal gas, the speed of sound is defined as follows:\n\na = SQRT(gamma*R*T), where gamma is the ratio of the heat capacities of the gas, R is the universal gas constant, and T is the absolute gas temperature. Similar correlations exist for the speed of sound in solids and liquids which depend on the density and thermophysical properties of the medium.

sound travels at about 580 miles per hour so if you travel at say 583 miles per hour then its supersonic, thats when you hear the boom on an aircraft as it breaking through the sound barrier

The speed of sound actually varies depending on the medium through which the sound is traveling. The speed of sound varies directly with the number of degrees of freedom of each molecule in the gas and varies inversely with the molar mass of the gas.\n\nThe speed of sound in air is approximately 331.5 meters per second or 741.5 mph.

Sound is a type of longitudinal, mechanical wave. They need a medium to propagate and will not travel through a vacuum. Sound travels at different speed in different media. The speed of sound is determined by the density (ρ) and compressibility (β) of the medium. Density is the amount of material in a given volume, and compressibility is a meaasure of how much a substance could be compacted for a given pressure. The denser and the more compressible, the faster the sound waves would travel. Therefore, the speed of sound is about four times faster in water than in air. The speed of sound in a medium can be determined by the equation  …\n\nv = (βρ)-1/2\n\nWhere …\n\nv is the speed of sound,\nβ is the bulk modulus of elasticity, and\nρ (rho) is the density.\n\nThe speed of sound can also be affected by temperature. Sound waves tend to travel faster at higher temperatures. I have found different values for the speed of sound in water in different sources. They range from 1450 to 1498 meters per second in distilled water and 1531 m/s in sea water at room temperatures (20 to 25 °C).

None, sound is a wave not a particle. Sound is just a wave of vibrations travelling through atoms.

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).

Because the speed of sound is set by the medium of sound (usually air) and hence your speed relative to the medium will make the speed of sound different if you're moving relative to said medium.\n\nThe speed of light is a constant for all observers, and light does not need a medium to travel through.

Measure the speed of sound by help of an echo, a stopwatch and a tape-measure. (depending on temperature it is about 430 m/s.\nRepeat your measurements at least 10x and have the average.\nGood luck\n\nTh

The speed of light in a vacuum is exactly 299,792,458 metres per second (or 1,079,252,848.8 km/h, which is approximately 186,282.397 miles per second, or 670,616,629.4 miles per hour; sometimes roughly 300,000 km per second). 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, in that the fundamental SI unit of distance, the metre, is defined 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.

The question asks nothing about the speed of sound in air compared with water. I believe that the answer is that sound will travel farther through air than water. \n\nMy reasoning is as follows:\n\nSound is a compression wave and its propagation is based upon atoms and/or molecues "bumping into" each-other in order to convey the energy of the sound. Now, with each collision between atoms/molecules, some energy is lost due to heat, so the more collisions there are (eg water), the more energy is lost. The fewer collisions there are (eg air) the less energy is lost. Of course, as everyone has pointed out, water is more dense than air, so there are more collisions per metre in water than in air, and so more energy loss per metre in water than in air.\n\nTherefore sound will travel farther in air than in water. \n\nAnother way to look at it is by taking it to the extreme. Let us imagine for a moment that there is a lonely molecule in outer space and we "bump" it with a spaceship. It will travel through space unimpeded, carrying that energy until it finds another molecule to bump into, maybe millions of kilometres away. So, that energy the spaceship imparted onto that molecule has travelled millions of kilometres. We can't hear a single molecule hitting our eardrums, but the effect is the same.\n\nAnyway, I hope that analogy helps.

The speed of sound in water (including seawater) depends on several factors, but most important is the the temperature of the water.  By measuring the time it takes for an acoustic signal to travel from a source to a receiver, one can determine the average temperature along the path followed by that sound signal. (Other factors that include sound velocity or travel time include salinity, pressure (i.e. pressure-induced changes in density), and ocean currents.)  By measuring the average temperature along many different paths, one can reconstruct a 3-dimensional "map" of the temperature distribution in the oceans.  \n\nBy following the changes in temperature over time, one can detect long-term changes in the temperature distribution and hence average temperatures of the oceans.

341m/s but it changes according to the weather conditions in humid climate it is faster as compared to dry.and yeah sound does not travel through vacuum\nspeed of sound in solids > liquids > gases
