How much time does it take a pulse of light to travel through 180\({\rm {\rm m}}\) of water?
Can you retype the equation please? I would love to help.
To determine the time it takes for a pulse of light to travel through a certain distance in a medium, you need to know the speed of light in that medium. The speed of light in a vacuum is a well-known constant, approximately \(299,792,458 \, \text{m/s}\).
However, the speed of light in a different medium is usually slower than in a vacuum. In this case, the medium is water. The speed of light in water is approximately \(225,000,000 \, \text{m/s}\).
Now, to calculate the time it takes for a pulse of light to travel through a given distance in water, you can use the formula:
\[
\text{{Time}} = \frac{{\text{{Distance}}}}{{\text{{Speed}}}}
\]
Substituting the given values, the time it takes for a pulse of light to travel through 180 meters of water would be:
\[
\text{{Time}} = \frac{{180 \, \text{{m}}}}{{225,000,000 \, \text{{m/s}}}}
\]
Calculating this equation will give you the answer.
