Answer #1:

To calculate the distance that light travels in water, we need velocity and time.

Velocity and time will enable us to correctly compute the distance.

===============================

Answer #2:

The "refractive index" of water is around 4/3 (look up). This tells us that . . .

-- the speed of light in water is about 3/4 of its speed in vacuum;

-- the time it takes light to cover a distance in water is 4/3 the time it would take

in vacuum;

-- the distance light can cover in water is about 3/4 the distance it can cover

in the same length of time in vacuum.

In whatever time it takes light to travel 1.0 meter in vacuum, it can travel

only about 75 cm in water.

How long will it take visible light to travel 250 km?

It will take light about 0.000834 seconds or 834 millionths of a second to travel 250 kilometers in vacuum, somewhat longer in any material substance.


What evidence do we have that light travel through a vacuum?

You create a vacuum in a lab, and then shine a light through it, and there is experimental proof that light travels through a vacuum. Alternatively, take the fact that light travels through space - if light could not travel through a vacuum, no light from the stars, the moon or the sun would ever reach our planet.


How long does it take light to travel 100 meters?

If the light is in a vacuum then it would take around 0.00000033 seconds.


How long would it take light to travel 1000km?

Light travels at a speed of approximately 299,792 kilometers per second in a vacuum. To calculate the time it takes for light to travel 1,000 kilometers, you can use the formula: time = distance/speed. Thus, it would take light about 0.00334 seconds (or 3.34 milliseconds) to cover that distance.


How long dose it take for light to travle 100m?

Approx 0.0000003336 seconds = 334 nanoseconds.


How long does it take for light to travel 100 miles?

Light travels at a speed of approximately 186,282 miles per second in a vacuum. To calculate the time it takes for light to travel 100 miles, you can use the formula: time = distance/speed. Thus, it takes light about 0.000536 seconds, or 536 microseconds, to travel 100 miles.


How long would it take light to travel 2000 miles?

Less than the blink of an eye; about 0.0107 second.


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 does light take to travel at light speed from the sum?

It takes about 8 minutes.


How long does it take light to travel in 1 hour?

It takes light exactly one hour to travel in 1 hour.


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.
