Physics for Kids The speed of sound is how fast the wave or vibrations pass through the medium or matter. The type of matter has a large impact on the speed at which the sound will travel. For example, sound travels faster in water than air. Sound travels even faster in steel. In dry air, sound travels at 343 meters per second (768 mph). At this rate sound will travel one mile in around five seconds. Sound travels 4 times faster in water (1,482 meters per second) and around 13 times faster through steel (4,512 meters per second).

- 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.

Q & A: Speed of Sound and Light What are speeds of sound and of light . We are doing research on lightning and thunder . 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.

Exactly how fast does sound travel through water, and why is it that sound travels faster in water than in air? 1 vote Vote for this answer. The speed of sound in water depends on the temperature. It can travel anywhere from 1480 meters per second to 1530 meters per second, which is about 4 times faster than that of the speed of sound through air. This is because water is more dense than air.

The Speed of Sound The Speed of Sound. A sound wave is a pressure disturbance that travels through a medium by means of particle-to-particle interaction. As one particle becomes disturbed, it exerts a force on the next adjacent particle, thus disturbing that particle from rest and transporting the energy through the medium.

2.3 Respiratory Regulation -continued 2.3.4 Peripheral Chemoreceptors . The peripheral chemoreceptors are the aortic and carotid bodies. They are anatomically separate from the carotid sinus baroreceptors and should not be confused with them. The peripheral chemoreceptors respond to changes in pO 2, pCO 2 and pH.

What travels faster, light or sound? Light travels faster than sound. In vacuum, the speed of light is about 3.0 x 10^8 m/s while that of sound is 0 m/s (sound needs a medium to travel, hence it cannot travel through a vacuum). In air, the speed of sound is approximately 340 m/s while that of light is the same as in the previous condition.

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).

Sound and Music Review The speed of a sound wave depends upon its frequency and its wavelength. In general, sound waves travel fastest in solids and slowest in gases. Sound waves travel fastest in solids (compared to liquids and gases) because solids are more dense. The fastest which sound can move is when it is moving through a vacuum.

How Many Miles Per Hour Does the Speed of Sound Travel? Quick Answer. The speed of sound varies depending on the type of medium through which it moves, explains Livescience. When traveling through Earth's atmosphere at sea level, and with a constant air temperature of 59 degrees Fahrenheit, sound travels at just over 761 miles per hour. Continue Reading.

- A: Sound travels as a back-and-forth vibration of the particles of its medium. It is a longitudinal mechanical pressure wave that varies greatly in its speed of travel and the distance it remains coherent, dependent upon the medium. Sound in air travels relatively slowly and for a short distance, while sound in a solid, such as the primary waves of an earthquake, travel extremely quickly and to great distances.

Speed of Sound in Air Sound Speed in Helium. The speed of sound in helium at 0°C is about 972 m/s, compared to 331 m/s in air. This is consistent with the general relationship for sound speed in gases since the density of helium is so much less than that of air.

Physics REGISTRY flashcards Since both waves are traveling through the same medium (ie., the air), they must have identical speeds. It is important to know that the speed of sound in soft tissues 1,540 m/s. That is, all sound waves travel nearly one mile per second through the body.

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). Because gas molecules move more slowly at colder temperatures, that slows the speed of sound; sound moves faster through warmer air.

- Sound waves are just vibrations of molecules, so the molecules or particles in a solid vibrate transversely. Sound also travels faster in solids, 5000m/s in steel, while only … 300m/s in air. This is because the particles are closer together meaning the energy has less of a distance to travel between the particles.

- Speed of sound is 330 m/s. So mach 1 is speed of sound or 330 m/s. Now mach 4 will be 330×4= 1320 m/s. This will be equal to 1.32 km per sec. Or 4752 km per hour. Or 2953 miles per hour. This is very very high speed in earth environment.

How does the speed of light compare to the speed of sound? The speed of light is roughly 882 thousand times the speed of sound. -- Sound takes about 4.7 seconds to cover 1 mile. -- Light takes about 0.0000054 second to cover 1 mile. -- In the time it takes sound to travel one mile, light travels 881,741 miles. During a thunderstorm, you see the lightning before you hear the thunder, even though they're caused by the same event. Another clue to an easy answer: Nothing is faster than the speed of light.
