Question: How fast is the speed of light compared to the speed of sound? The speed of light is much faster than the speed of sound. Sound moves at 343 metres per second (thats about 770 miles per hour!). The speed of light is a little trickier. In a vacuum it is roughly 300 000 000 metres per second (so nearly 900 000 times faster than sound!). However, when light moves through air or glass it gets slowed down a little bit so light moving through glass moves at 200 000 000 metres per second which is still 580 000 times faster than sound.

Science Articles & Cool Facts Well imagine going 500,000 times faster than a concorde and you have a speed nearing 299,792,458 meters per second. This is the speed of light as it travels through a vaccum which is so fast that if you were able to move at this speed you could go around the earth 7 times in just 1 second, now that’s fast! Obviously the speed of light passing through liquids and solids is slower but even then the speed of light is phenomenal.

What travels faster? Light or sound? The speed of sound is 344 meters per second or 770 mph...that of course is in the open air...under water..it's much faster. The speed of light travels 186,000 miles per second...so light is a whole lot more faster than sound. Sound at sea level travels at 1087 feet./second, while light in a vacuum travels 186,292 miles/second. light travels faster. Light travels at 185861 miles per second, at about 760 miles per hour.

- Slower. Nothing goes faster than light, which travels at a speed of 300.000 km/second, or 186.000 miles/second. Sound travels through our air at the speed of about 343 metres/ … second, or 0,343 km/second, which is 1.125 feet/second, which is in its turn about 0,213 miles/second.

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.

- Light travels at 186,000 miles per second in a vacuum. So the light from a flash of lightning travels at the speed of light in air, which is slightly less than the speed of light in a vacuum (e.g. space) <br /><br /> But lightning itself travels nowhere near as fast as the speed of light.

What determines the speed of light? Why is the speed of a massless particle a fixed constant, independent of particle type, and why is this speed so integral to Relativity? Use the interactive Speed of Sound calculator below to see the effect of temperature on sound's velocity. For comparison, the speed of light in a vacuum is 299,792,458 meters per second or 186,000 miles per second (669,600,000 mph), which is roughly 870,000 times faster than the speed of sound.

Why Does Light Travel Faster Than Sound? The denser the medium, the faster sound will travel. Sound travels through air at the speed of 1,115 feet per second, through water at 4,757 feet per second and through iron at 16,404 feet per second. Light travels at 186,411 miles per second in vacuum. In water, the speed of light drops to 139,808 miles per second.

How Fast Does Light Travel? | The Speed of Light Einstein's theory of special relativity sets of the speed of light, 186,000 miles per second (300 million meters per second). But some scientists are exploring the possibility that this cosmic speed limit changes. The speed of light in a vacuum is 186,282 miles per second (299,792 kilometers per second), and in theory nothing can travel faster than light. In miles per hour, light speed is, well, a lot: about 670,616,629 mph. If you could travel at the speed of light, you could go around the Earth 7.5 times in one second.

Did man really walk on the Moon ??? The speed of light is 300,000,000 meters per second, but the speed of sound is only about 340 meters per second. If you are watching fireworks that are about a kilometer (1000 meters) away, the light takes only 3 millionths of a second to reach you. The sound takes about 3 seconds. You can tell how many kilometers away fireworks are exploding by starting to count seconds as soon as you see an explosion.

What is the Speed of Sound? Simply put, the denser the material the faster the sound waves travel. The speed of sound through air at ground level is approximately 760 mph, or approximately 1100 feet per second. The old lightning/thunder trick offers a good example. For approximately every five seconds the sound travels is one mile.

- Light travels fastest in pure vacuum, at the speed of light of 299 792 458 m/s (670,616,629 mph). If there are any particles, some light will reflect off of those particles … and bounce around, reducing its speed. With combinations of certain gasses, it is possible to slow light down to extremely low relative speeds.

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.

- Confidence votes 417. In vacuum, the speed of light is a constant c = 300 000 000 m/s. In a transparent medium, light slows down by a factor of 1/n where n is called the refractive index of the medium.30,000 to 1. Sound travels roughly 1/5 of a mile per second in air. Light travels 186,000 miles per second in a vacuum. In five seconds sound … travels one mile. In five seconds, light travels 930,000 miles in a vacuum.

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).
