How fast does sound travel? How fast does it travel? Sound travels about 1500 meters per second in seawater. That's approximately 15 football fields end-to-end in one second. Sound travels much more slowly in air, at about 340 meters per second, only 3 football fields a second. Unfortunately, the answer is really not quite that simple. The speed of sound in seawater is not a constant value.

- The speed of a wave is the rate at which vibrations move through the medium. Sound moves at a faster speed in water (1500 meters/sec) than in air (about 340 meters/sec) because the mechanical properties of water differ from air.

- Sound waves need to travel through a medium such as a solid, liquid, or gas. The sound waves move through each of these mediums by vibrating the molecules in the matter. The molecules in solids are packed very tightly.Liquids are not packed as tightly as solids.And gases are very loosely packed. The spacing of the molecules enables sound to travel much faster through a solid than a gas. Sound travels about four times faster and farther in water than it does in air.This is why whales can communicate over huge distances in the oceans. Sound waves travel about thirteen times faster in wood than air.iquids are not packed as tightly as solids. And gases are very loosely packed. The spacing of the molecules enables sound to travel much faster through a solid than a gas. Sound travels about four times faster and farther in water than it does in air.

Why does sound travel faster in water than air? So, all other things being equal, the fact that water is much more dense (about 800 times more dense) than air would tend to make sound propagate far more slowly in water than in air.

- Sound waves are like light and water waves in other ways too. When water waves traveling long distances across the ocean flow around a headland or into a bay, they spread out in circles like ripples. Sound waves do exactly the same thing, which is why we can hear around corners.

- The speed of sound is the distance travelled per unit time by a sound wave propagating through an elastic medium. The SI unit of speed is the metre per second (m/s). In dry air at 20 °C, the speed of sound is 343.2 metres per second (1,126 ft/s).This is 1,236 kilometres per hour (768 mph; 667 kn), or a kilometre in 2.914 s or a mile in 4.689 s.he speed of sound is the distance travelled per unit time by a sound wave propagating through an elastic medium.

Speed Of Light vs. Speed Of Sound Its value is measured at 299,792,458 meters per second. Speed of sound on the other hand, is the distance that sound travels through an elastic medium. In dry air with a temperature of 20 °C, the speed of sound is measured at 343.2 meters per second. This translates to 1,236 kilometers per hour, or about one kilometer every three seconds. As mentioned previously, the speed of light is denoted by a “c”, which stands for constant.

- The speed of sound depends on the material the sound is passing through. Below is the approximate speed of sound (in feet per second) for air, water and steel: Write a program that asks the user to enter “air”, “water”, or “steel”, and the distance that a sound wave will travel in the medium. The program should then display the amount of time it will take. Prompts And Output.

What Is the Speed of Sound in Fps? Mach 1 rises with the density of the medium. In 25-degree Celsius fresh water, sound propagates at 4,940.1 feet per second. In sea water Mach 1 is equal to 5,148 feet per second, or nearly 3,600 miles per hour. In air the speed of sound is a function of temperature only. Though supersonic aircraft measure speed as a function of external air pressure, this is only an approximate method caused by technical limitations.

What does Adobe Reader do? For example, a writer can create a Microsoft Word document on a Windows machine, convert it into a PDF file and give it to a person using a Linux machine and they can use Adobe Reader to read it. The Linux user doesn't have to have Microsoft Word to read the document. The Reader is free, but Acrobat costs money.

Q & A: Speed of Sound and Light A: Holly, The speed of sound through air is about 340 meters per second. (The speed of sound in water is about 4 times faster than this). The speed of light in air is about 300 million meters per second.

What is the Speed of Sound? These 10 facts about space will blow your mind. The speed of sound varies depending on altitude, temperature and the medium through which it travels. For example, at sea level in a standard atmosphere, at a temperature of 59-degrees Fahrenheit (15 Celsius), sound travels 761 miles per hour (1,225 km/p/h).

Speed of sound The speed of sound in air (at sea level) is about 1220 km/h (760 mph or 340 meters per second). Compared to light waves, sound waves creep along at a snail's pace—about a million times slower.

- Through which substance does sound travel fastest? A: Sound travels fastest through solids. The density of the substance that sound waves move through, as well as its elastic properties, determine its speed.

They also travel faster on hotter days as the molecules bump into each other more often than when it is cold. Learning outcomes. The students will: identify mediums that sounds can travel through and classify them from slowest to fastest.

- Since the molecules vibrate faster, sound waves can travel more quickly. The speed of sound in room temperature air is 346 meters per second. This is faster than 331 meters per second, which is the speed of sound in air at freezing temperatures. v is the speed of sound and T is the temperature of the air.

What Is the Speed of Sound? The speed of sound varies depending on the temperature of the air through which the sound moves. 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).

Speed of sound However, the speed of sound varies from substance to substance: sound travels most slowly in gases; it travels faster in liquids; and faster still in solids. For example, (as noted above), sound travels at 343 m/s in air; it travels at 1,484 m/s in water (4.3 times as fast as in air); and at 5,120 m/s in iron (about 15 times as fast as in air).

Can you calculate how far away lightning struck by thunder? ­As you can see, the speed of sound changes depending on the temperature and the humidity; but if you want a round number, then something like 350 meters per second and 1,200 feet per second are reasonable numbers to use. So sound travels 1 kilometer in roughly 3 seconds and 1 mile in roughly 5 seconds.

In which medium does sound travel fastest? Rating Newest Oldest. Best Answer: Sound travels fastest through solids. This is because molecules in a solid medium are much closer together than those in a liquid or gas, allowing sound waves to travel more quickly through it. In fact, sound waves travel over 17 times faster through steel than through air. The exact speed of sound in steel is 5,960 meters per second (13,332 mph)! But, this is only for the majority of solids. The speed of sound in all solids are not faster than in all liquids.

- Light waves travel in vacuum with the speed of light c = 299792458 m/s or 983571056 ft/s. Sound waves travel at 20°C (68 … F) with the speed of sound c = 343 m/s or 1125.33 ft/s. So light travels 874,030 times faster than sound. Don't forget that sound needs necessarily air as a medium.

Sound: Facts Sound travels in waves! Sound waves usually travel through air or water, but they can also travel through solids too, like walls or furniture. Sound waves use the matter to move the vibrations.

How Far Can Sound Travel? The distance that a sound wave travels can be figured by multiplying the speed of the sound (approximately 345 meters per second under normal atmospheric conditions at a temperature of 20 degrees Celsius) by the time it takes for a person to hear it once the sound is initiated.

Physics of ultrasound Velocity through a given medium is inversely related to the density and directly related to stiffness of that medium. Ultrasound waves travel faster through a stiff medium, such as bone. In echocardiography, the velocity of sound is assumed to be approximately 1,540 m/sec (or 1.54 m/msec). Sound waves travel through the air with speed of 330 m/s. The typical velocities for different tissues are provided in table 1.
