In other words, sound can travel about a mile in five seconds.Sound waves can travel through different mediums at different speeds. That means that sound waves can travel about 1,100 feet in one second. The speed of sound is constant in the same sense that the mass of an object is constant. The speed of sound is about 1,100 feet per second in air. Sound travels at different speeds in different substances. SOUND SPEED IN DIFFERENT MEDIUMS Sound’s speed in colloquial speech refers to the speed of sound waves in the air. How long does it take sound to travel 50 feet?įoot Per Second to Speed Of Sound Conversion Table Feet Per Second The contemporary value for the speed of sound in dry air at a temperature of 0 ☌ (32 ☏) is 331.29 meters (1,086.9 feet) per second. … If you have light that's going through a media, it can travel slower than that. Light will travel through a vacuum at 300 million meters per second. It's faster through water and it's even faster through steel. The speed of sound through air is about 340 meters per second. What is the speed of sound at 35000 feet?Ībout 660 mph At 35,000 feet, the cruising altitude of a typical passenger jet, sound travels at about 660 mph (1,062 kmph). Visible light can also travel through other things besides through air and through space. The speed of light as it travels through air and space is much faster than that of sound it travels at 300 million meters per second or 273,400 miles per hour. At Mach 10 it is 11000 fps so time to travel 100 Feet is 0.0091 Sec. First we convert the units 750 mph = 1100 feet per second. The speed of sound is 750 miles per hour near sea level then drops to 650 mph as altitude increases then continues up to 1000 mph with increasing altitude. How long does it take sound to travel 100 ft?
Because gas molecules move more slowly at colder temperatures, that slows the speed of sound sound moves faster through warmer air. What is the speed of sound How fast?ħ61.2 mph On Earth, the speed of sound at sea level - assuming an air temperature of 59 degrees Fahrenheit (15 degrees Celsius) - is 761.2 mph (1,225 km/h). At 20 ☌ (68 ☏), 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 2.9 s or one mile in 4.7 s. What is the speed of sound at feet per second?ġ,125 ft/s The speed of sound is the distance travelled per unit of time by a sound wave as it propagates through an elastic medium. To put that in perspective, its amazing to realize that bullets travel over twice the speed of sound If you shoot a gun at a target several yards away, its easy to think of bullets traveling in a straight line. Thats equivalent to over 1,800 miles per hour. If we consider the atmosphere on a standard day at sea level static conditions, the speed of sound is about 761 mph, or 1100 feet/second. The fastest bullets travel more than 2,600 feet per second.
