Speed of Light
======================
Answer #2:
Many modern aircraft cruise at speeds greater than that of sound.
The adjective used to describe such travel is "supersonic".
Speed of light in air ~ speed of light in vavuum = 3,00 *10^8 m/s speed of sound in air ~ 330 m/s. Speed of light is faster than sound in air
The speed of sound in air is about 300 meters per second. (320 is closer still). ..The speed of light in a vacuum is 300 000 000 meters per second.So the speed of light in a vacuum (in air it is only slightly different) is about one million times the speed of sound in air.
Running speed is about 3 m/s Light speed is about 300000000 m/s That's 10^8 times faster
We see the firework works first because the because burning emits light . It is a fact that it travels faster than sound . So the sound energy produced during the burning of fire work reaches us late . So we hear the sound after vizualizing it.
How fast is sound and light?The speed of sound is at about 344 m/s and the speed of light is at about 3 X 108 m/s. If you would like to test it out, wait for a thunderstorm. The lightning and the thunder start at the same place while the lightning is faster. That will demonstrate the speed difference of light and sound.Light takes 8 1/2 minutes to reach us from the Sun.The speed of sound varies with the relative motion of the observer but the speed of light is constant regardless of the relative speed. See Einstein's special theory of relativity.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.Sound crawls.Sound speed is about 700 mph. (about 1/5th of a mile per second)Light speed is about 186,000 mps.Light goes about 930,000 times quicker.If someone claps their hands 250 feet away, light can go 8½ times round the world while you wait to hear it.Speed of light is a lot faster...the speed of light goes 299,792,458 meters per sec and the speed of sound goes 343.2meters per sec
Speed of light in air ~ speed of light in vavuum = 3,00 *10^8 m/s speed of sound in air ~ 330 m/s. Speed of light is faster than sound in air
Light; The speed of light is 300,000 km/s yet the speed of sound is just 343 m / s
Speed of Light Speed of Sound: 330m/s Speed of Light: 299 792 458m/s
No. It's the other way around ... sound is much slower. The numbers for each are thus: * Speed of Sound: 340.29 m/s * Speed of Light: 299,792,458 m/s Yup - light is faster ... much faster. You've never heard in the comic books "faster than the speed of light"??????
Light travels at approximately 3x108m/s whilst sound travels only at 343m/s. So which do you think is the faster one?
Because light travels significantly faster than sound. Speed of light (in vacuum) = 299 792 458 m/s Speed of Sound (at sea-level ) = 340.29 m/s
No!! Speed of light: 299 792 458 m / sSpeed of sound: 340.29 m / s
Speed of light in vacuum is 299792458 m/s or 983571056.43045 ft/s.Speed of sound in air of 20°C or 68°Fahrenheit is 343 m/s or 1125.32808 ft/s.You see that light is 874030 times faster than sound.
The speed of sound in air is about 300 meters per second. (320 is closer still). ..The speed of light in a vacuum is 300 000 000 meters per second.So the speed of light in a vacuum (in air it is only slightly different) is about one million times the speed of sound in air.
Which of them travel faster - light or sound waves? 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. Light does not need a medium; vacuum is O
light . . . 3 x 108 m/s sound . . . 343 m/s light-speed x sound-speed = 102,900,000,000 meters2/second2 This quantity has no physical meaning or application.
Light travels much, much faster than sound. Light travels at 299792458 m/s while sound only goes 340.29 m/s.
