Scientists have defined the speed of light in a vacuum to be exactly 299,792,458 meters per second, which is 983,559,096 feet per second. So a ray of light in a vacuum could travel a foot in 983,559,096 millionths of a second, which is pretty fast.

The speed of light in a vacuum is 3108 meters per second How long does it take light to reach a distance of 455m?
To calculate how long it takes light to travel a distance, you can use the formula: time = distance / speed. In this case, for a distance of 455 meters and a speed of 3108 meters per second, it would take approximately 0.147 seconds for light to travel that distance.
How long dose it take for light to travle 100m?
Light travels at a speed of approximately 299,792 kilometers per second in a vacuum. To travel 100 meters, it would take light approximately 0.000000336 seconds.
How long does it take light to travel 100 meters?
Light travels at a speed of approximately 299,792 kilometers per second in a vacuum. Therefore, it would take approximately 0.000335 seconds for light to travel 100 meters.
The velocity of light is 3 x 10000000000 cm per second How long will it take a beam of light to travel 10 cm?
It would take (10 divided by 30,000,000,000) seconds to travel 10 cms, which is 0.000000000333333 of a second (approximately!) In nanoseconds this is 1/3rd of a nanosecond. For all practical purposes, for such a small distance, one could consider that the beam of light (in space) would travel that distance almost in an instant. It's that fast!
How many seconds would it take to travel to the sun if you traveled at the speed of light when the radius of the earth is 6371 km equals 3960 mi?
The distance from the Earth to the Sun is approximately 93 million miles (about 150 million kilometers). At the speed of light, it would take light 500 seconds to travel this distance. This is because light travels at a speed of about 186,282 miles per second or 299,792 kilometers per second.
How many nanoseconds does it take light to travel 1 foot?
It takes 1.3 to 1.4 nanoseconds for light to travel 1 foot.
How much time does it take light to travel one foot?
One nanosecond.
How long does it take to travel 1500 miles on foot?
3 months
How long does it take to travel 1 light year?
It will take 1 year, as soon as you and Albert work out how to travel at the speed of light. ;)
How long will it take to travel 30 miles by foot?
That depends on the speed at which one is traveling.
How long does it take light to travel in 1 hour?
It takes light exactly one hour to travel in 1 hour.
How long does light take to travel at light speed from the sum?
It takes about 8 minutes.
How long will it take to travel to the milky way in nanoseconds?
(Assuming the you are planning on going the speed of light)3,153,600,000,000,000,000,000or3.1 sextillionor3.1 thousand trillionI assume however that you thought this number would be lower. As fast as light is, it will still take around 100, 000 years to cross the galaxy. In one nanosecond light will travel around 1 foot.
