How long (in ns) does it take light to travel 1.00 m in vacuum?

What distance does light travel in water during the time that it travels 1.00 m in vacuum?

distance= speedlight*time

solve for time.

To calculate the time it takes for light to travel a certain distance, we can use the formula:

Time = Distance / Speed

In this case, we need to find the time it takes for light to travel 1.00 m in vacuum. The speed of light in a vacuum is approximately 299,792,458 meters per second (m/s).

So, the time it takes for light to travel 1.00 m in vacuum is:

Time = 1.00 m / 299,792,458 m/s

We can calculate this using a calculator or a numerical computation software. The result will be the time in seconds (s). To convert it to nanoseconds (ns), we can multiply it by 1,000,000,000, since there are 1 billion nanoseconds in a second.

Next, let's calculate the distance light travels in water during the same time it takes to travel 1.00 m in vacuum. The speed of light in water is slightly slower than in a vacuum. It is approximately 225,000,000 meters per second (m/s).

To find the distance, we can use the formula:

Distance = Speed x Time

We already have the time from the previous calculation (in seconds), so we can plug it into the formula:

Distance = 225,000,000 m/s x Time (in seconds)

Calculate this to find the distance light travels in water during the given time.

I think you mean PHYSICS, not physic. There's an amazing difference between the two.
