123km
because i already know
you can see it before you hear it light lightening.
bcoz we all know the sunlight reached to us in second which is about 91 million km. from earth.
but we can't hear the voice of anything after some distance.
because the speed of sound is just much fatser and tha answer was just found...:)
because light moves faster than soun d because sounds can have slow beats
because when you see lightning you always see it before you hear it
Beacause I like lot's of Chicken

Because when compared to a constant light is 870,000 times faster than sound, and because it would be impossible for sound to be high enough in altitude to match the speed of light without being out of earths atmosphere.
because we're not stupid!!!
Speed of light is faster since light particles or light waves can travel through vacuum and it doesn't need a medium to transfer or travel so it can move fast while sound waves still need medium to travel. And also, light is mechanical wave while sound is transverse.
light travels at a speed of 300,000km/sec whereas sound travels at a speed of 300m/sec which is much slower than the speed of light.
Its value is measured at 299,792,458 meters per second.
sound is measured at 343.2 meters per second
Duh! Within the standard medium, the speed of light is 873521 times the speed of sound.
because when we go away from the source of sound it seems slow but light is not like this.
oooookkkkk
obvious answer
dont even ask
Because it's true!
nunya bidnes
has a faster velocity
light velocity is higher than sound velocity
The "c" is approximately 1,000 times faster the sound.
Because it makes sense
Because the difference in relative speeds expressed above indicate light moves roughly one million times faster than sound.
Light travels faster
because its faster, ya dip
**** wrinkle
Light is fixed, sound is variable
During a thunderstorm, I see the lightning before I hear the thunder.
Because it's true
speed of light 299,792,458 meter per second
speed of sound 343.2 meter per second
Because I'm not an idiot
the speed od light is 1 million times faster than sound.
Measured at 299,792,458 meters per second
I guessed
I'AM SMART
Light travels faster than sound
Speed of light is 300 mil meters/sec
Speed of sound is only 345 meters/sec
its common knowledge
Lol
the thunder and lightening theory...you always see lightening before the thunder
Numbers never lie. The speed of light is so fast that it is impossible for the sound to "catch up." The speed of light is constant, but speed of sound, or Mach 1, can be altered, changed, and can be utilized in modern aerodynamics, but the speed of light cannot be achieved for that particular use.
When Mach 1 is attained, the sound barrier is broken and a sonic boom is the result. Sonic booms could seriously damage the human ear and body, and even cause damage to the environment around you since sound waves can "break things apart." It's like an unstoppable force of energy destroying a city in a matter of seconds.
Reaching the speed of light, or C, in theoretical terms, could be instant time travel to the future, especially if you are in a vehicle which can resist the side effects of going at such a speed. However, this amazing feat is only achieved in works of fiction, and not in real life. At least that's as far as we know...
Light is energy that can travel in a vacuum... Sound requires matter to travel... And is slower because it travel by vibrations...
n
You see light before you hear sound
its because I read the article. First I thought it was sound. I think.
oh and because did you know that if the sun went out it would take us 8 minutes to figure it out? That means it would take 8 mins for the darkness to reach earth. :0
because it is
Skkrt
The lightening always comes before the thunder
It makes sense
Because i did
The speed of light is faster than the speed of sound.
Because it's said so in the article
LET ME GIVE THE EXAMPLE OF LIGHTNING......................WE CAN SEE THE FLASH OF LIGHTNING EARLIER THAN WE CAN HEAR THE SOUND OF IT.............
Speed goes faster at 3 x 10e8 metres per second whereas sound goes at roughly 350 metres per second and depends on altitude and temperature among other things.
Sound consists of longitudinal waves whereas light consists of transverse waves as such sound needs a material to travel, light can actually move in a vacuum.
rfgdgfgvdfd
as we know that sound travels more slower (about 330 m/s)than light(which travels at a speed of 3 lakh kilometer
Duhh
Light travels at almost 300,000,000 m/s and sound only travels at 340 m/s.
because speed of light travel at 299,792,458 meters per second vs speed of sound travel only 343.2 meters per second.
Its faster
Because light travels through a vacuum. Whereas sound needs a medium to travel through.
it can travel 299,792,458 meters per second compared to 343.2 meters per second for speed of sound. MNot even close.
Because everyone knows that
because light is more energetic than sound
because light of speed is instant
It's a secret. "C" you later...
light travels 300,000 kilometers per second
sound travels 1 kilometer every 3 seconds
I picked speed of light because speed of light is the well know thing that can travel very fast.
because it is just that good
.
obious
Because I took science classes growing up and wanted to be a science teacher.
Duh...
because it does not need any medium to travel
because it is dummy **** hole
contact me. I think you know what time travel is. Rkossarian@gmail.com. Its urgent.
The speed of light has a higher frequency, meaning it can travel much faster compared to the speed of sound, which has a longer wavelength
I don't give a ****
I'm guessing . I think so .
because the speed of light travels at about 300,000 k / second and the speed of sound 300m / second.
Lightning appears before the thunder
Light is 300,000km/s goddam nothing we could conceive we made things which travel fast but light is the fastest thing aside from teleportation
you see the lightning strike before you hear it
Well, would you rather have $299,792,458 or $343.20? :)
chegg
I'm not stupid
XD
cos i aint Dumbo
because it just told me in the first paragraph... duh
there is more metres measured than speed ofsound which means it travels quicker and faster.
Light is an matter of electromagnetic matter which the electrons travels its maximum speed around 299792456 m/sec
Speed of light travels 299,792458 meters per second while speed of sound travels 343.2 per second
The reason why I chose this is because the speed of light is about 300 million meters per second and the speed of sound is 343.2 meters per second and so the speed of light is faster.
Because it said 299,792,458 meters per second. 343.2 meters per second? Yeah, it's faster.
Because Light is thunder and thunder is faster than sound. When there is a storm you see the thunder before you hear t.You don't know that you can see the fireworks before hearing them, that is because light is so fast.
mep
I'm learning...
Its obvious.
I'm a kid and I've known this since I was like 7
is a physical constant. Machs related to an elastic ratio.
because it is
Y has a long tail and two branches
Atmosphere is a greater barrier for sound than light.
no
