How many times does light go around the Earth in one second?
Appr. answer = 7.4 times/sec
equation used: time = distance/rate..... x seconds = (circumference of earth)/(speed of light).....
x = (4.00727E7 meters)/(3.00E8 meters per second)
x = .1335 seconds
.1335 seconds is how long it takes light to orbit earth once.
1/.1335 = 7.4
light travels around the earth ~7.4 times in one second.
Hope this helps
(Of course, light would never travel like this, except around a body with enough mass to curve space-time enough for light to be trapped in that orbit, though it would be a very unstable orbit and would eventually escape or fall spiralling).
If light were to go in a circle around the earth it would go around the earth about 7 3/4 times in a second.
light can travel around earth about seven times
Light travels at: 299,792,458 metres/second in the vacuum of space. Around the earth roughly 7.5 times per second. 3600 sec. in an hour. Around the earth roughly 27,000 times in one hour.
Light doesn't actually go around the Earth; light travels in generally straight lines. But if light DID go around the world, it could go around the world seven times in just less than one second.
To reach earth from the sun, light takes about 8.3 minutes. To circle the earth once, light takes 0.13 seconds, so light can circle the earth about 7.5 times per second.
Speed of light : 3 * 108 metres per second Earth circumference : 4.003 * 107 metres > Distance travelled by light in 1.1 seconds = 3.3 * 108 metres Revolutions of the earth = (3.3 * 108) / (4.003 * 107) = 8.24 times
About 300,000,000 meters per second - enough to go around the Earth 7.5 times in a single second.
at a little over 186000 miles per second, about 7 times.
About a second. The circumference of Earth is about 40,075 km. Light travels at about 299,792 km/s. So to find how long it takes to go around 7.5 times, we multiply the circumference of the Earth by 7.5. Then take that answer and divide it by the speed of light, which equals 1.0026 seconds.
Light has a speed of almost 300,000 km/sec. The circumference of Earth is 40,000 km. Therefore, in theory, light can go around Earth 7.5 times per second. However, since light travels in a straight line, it will not go around the earth unless helped by being reflected from other bodies.
Exactly 299,792,458 meters per second - enough to go around the Earth 7 1/2 times in one second.
light is faster than the messages to the brain . a proof is that in a second light travels 7 times around the planet earth. but the messages from the nerves to the brain is also very fast.
Light travels at 300,000 km/sec. (in a vacuum). That is enough to go 7 1/2 times around the Earth in a second (but note that light has a natural tendency to go in a straight line).
The second nearest star to Earth is Proxima Centauri, 4.25 light years away and 270,000 times farther away than the nearest star, the Sun!
Without a time limit I can go around the earth as many times as I want. Light is able to travel around the earth in 0.002224 sec. Light can travel roughly 8.9810749 times. Id say 9 times but im a free thinker. Light Speed: 299792458 m/s Earth Distance: 24,859.82 miles
Light travels at about 1,079 million km per hour but it is much easier to say that it travels at about 300.000 km per second which is about 6 times around the earth.
Of course, microwaves travel in straight lines, not around the Earth, but just like any other electromagnetic wave, like light or X-rays, the speed of microwaves is about 300,000 kilometers per second. That distance corresponds to roughly 71/2 times the Earth's circumference.
If the earth is 25000 miles around and lightning travels at 670616629.384 miles per second how many times would it circle the earth in one second?
LIGHT travels at about 670,616,629.384 miles per HOUR, not per second! Converting m.p.h. to miles per second, then the approximate speed of light would be about 186,282 miles per second. IF lightning travels at the speed of light (which it doesn't!) then 186,282 miles in one second divided by the approximate circumference of the earth, i.e. 25,000 miles, equals 7.45, or say seven and a half times round the earth, or once every 1/7.45 =… Read More
Approximately 75,000 light years. To give an idea of how far that is. A beam of light will travel around the Earth 8 times in one second. So light from the far side of the galaxy left when man was first creating tools from flint.
No. At sea level the speed of light is about 908280 times faster than the speed of sound. Also, if you think of it this way..... Light can go around the earth 5 times in one second, while speed of sound is about as fast as a commercial jet plane.
Light takes 1.26 s to travel from the moon to Earth in an experiment What is the distance between them at this time?
Light travels at 300,000 km per second, or 186,000 miles per second. Multiply the speed of light in your preferred units times the time to get the distance.
If you were travelling faster than the speed of light then yes, but if you were not travelling at light speed you would not. Travelling at light speed can take you around the world 7 times a second.
299 792 458 metres per second (m/s) 186,282 miles per second 93 million miles in 8 minutes 5,865,696,000,000 miles per year (one light year) This is fast enough to travel around the Earth about 30 times per second!
ANSWER Additional Info: one light year measures about six trillion miles. 8-x ANSWER A bunch. A light-year is the distance light travels in one year, and at 186,000 miles per second, a L-Y is a pretty long way. Since the earth is about 24,000 miles around at it's fattest point, light can, if it wanted to, go around the earth ONE time in...let's see...24000 miles divided by 186000 per second...carry the one...just under 1/10 of… Read More
Since you travel 5.86 x 10^12 miles in one light year, and the circumfrance of the earth is approximately 24902.4 miles You would be able to travel around the earth 235258223.6 times or Over 235 million times.
About 7.5 times in one second. (7.4, to be more accurate)
A star that is 970 light years away from the Earth is ten times more distant from the Earth than one at 97 light years distant. At a light speed of 300,000,000 metres per second, that's a long way in anyone's language. Yes, that's three hundred million metres per second.
Light could travel seven and a half times around the world in one second.
The equator is 40,075,020 meters long (40,075.02 km). Light in a vacuum travels 299,792,458 meters per second. Realize that unaided light would not travel along the equator at ground level like this; this is just for comparison. Given the figures above, something moving at light speed would make it around the equator about 7.48 times in one second. Quite a clip, I would say.
About 7 times per second
Approx 1/8 seconds.
Why the room light comes on at almost the same instant as you close its switch despite the very slow movement of the electrons in the wires connecting it to the mains supply?
Electrons are not that slow and light travels at...well... the speed of light, which is so fast that it can go around the entire earth 7 times in a second.
A "Light Year" is a measure of distance. It equals approximately 9.5 trillion kilometers or 5.9 trillion miles. The Speed of Light (C) is: 299,792,458 meters per second 17,987,547,480 meters per minute 1,079,252,848,800 meters per hour 186,282 miles per second (~ 71/2 times around the Earth in one second) 11,176,920 miles per minute 670,615,200 miles per hour
The question is an example of how a legend or folk tale gets distorted through retelling. The figure of "seven and a half" is a phrase the questioner heard somewhere in the past, in connection with the subject of light traveling around the world. It's the number used to convey a concept of the speed of light. The speed of light is such that when traveling at that speed, an object would circle the earth… Read More
Light travels faster than the messages to your brain . Light is the one of the fastest things in the universe , so light is faster than the messages from your nerves to the brain . Another fact about light is that it can travel 7 times around earth in a second , but the brains also think quite fast for us humans !
7 times well actually 7.4649145545156827587037754677922
Moonlight takes about 1 1 2 second to reach earth whereas this other type of light takes about 8 minutes what is it called?
It's not the type of light; it's how far it has to go. Sunlight takes about 8 minutes and 20 seconds to reach Earth. Since 8 minutes and 20 seconds is about 333 times as long as 1Â½ seconds, and since the speed of light is constant in a vacuum, that means that the sun is about 333 times as far from Earth as the moon.
The average distance from the Earth to the Moon is 238,857 miles, about thirty times the diameter of the Earth. Earth's diameter is about 8,000 miles. Earth's circumference is about 25,000 miles. Earth's distance from the moon is 1 second (in light years).
None. In the absence of an extremely strong gravitational field, like that of a black hole, light will travel in a straight line. It cannot, therefore curve around the world. In vacuum, in one second light can cover the distance equal to 7.5 times around the world.
It travels at a little less than 299,700 kilometres per second. However, near earth it travels in a straight line so it does not travel around the world.
It doesn't have a velocity! However, in theory, one could say that darkness is the only thing that replaces light!! So as light goes away, darkness takes its place!! So darkness probably travels at the speed of light :D - 186000 miles per second (that's about 7.5 times round the earth in a second)
Light travels at approximately 186,000 miles per second, or approximately 3,000,000 (3-million) meters per second, or almost 1,000,000,000 (1-billion) feet per second. That's about 1 nano-second (1 billionth of a second) per foot. Light almost always travels in a straight line, but light is affected by gravity, and the path of the light can be "bent" (curved) as the light passes near large planets, or stars, or "black-holes". The distance around the earth at the… Read More
It can't rotate that fast, since the linear speed at the equator would exceed the speed of light by far. The fastest it could rotate in theory would be about 7 times a second. In that case, it would break apart immediately.
Light travels around the Earth 7 times per second. This light bounces between your eyes and the mirror in a bright place to produce an image. The shinier and undamaged the mirror is and the more light there is, the clearer the image will be. That's why it's harder to see an image in a dim room, or on a cheap/scratched mirror.
A light wave completes a billion cycles in one second.
55 times per second. (globaly)
8.6 million times a day or 100 times a second.
3x108 metres per second is the speed of light roughly, so 9 times that is 2.7x109 metres per second or 2,700,000,000 m/s
No. A light year is the distance that any light can travel in a year. It's about 63 thousand times the distance from the sun to Earth. The light from the sun takes about 8 minutes to travel to the Earth.
