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".
The speed of sound in dry air at 20 °C (68 °F) is 343 meters per second (768 mph). There are several things that travel quicker than this speed, some being:
Light travels much faster than sound.
For example, when lightning strikes, you can see the lightning before you hear the thunder from the lightning.
The speed of light is almost a million times faster than the speed of sound. Lots of things are faster than the speed of sound. It is considered basically impossible for anything to travel faster than the speed of light.
For example, several types of airplanes travel faster than that; Earth's movement around the Sun is 30 kilometers/second, which is several times faster than the usual speed of sound; and of course, the speed of light is roughly a million times as fast as the speed of sound.
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.
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.
Running speed is about 3 m/s Light speed is about 300000000 m/s That's 10^8 times faster
The speed of light is 299,792,458 m/s. The speed of sound varies. But at sea level, it is 340.29 m/s. 299,792,458 m/s + 340.29 m/s = 299,792,798.29 m/s. Note: m/s = meters per second
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"??????
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 travels at approximately 3x108m/s whilst sound travels only at 343m/s. So which do you think is the faster one?
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.
Under normal circumstances, no. The speed of light in a vacuum is roughly 300,000,000 meters/second, while the speed of sound through air is 340 meters/second. However light does not travel 3x109 m/s inside a medium, and recent experiments have shown there are ways to slow light down to a crawl. In such a medium, usually a crystal structure, sound could indeed travel faster than light.
