Which of the following techniques can be employed to determine the speed of light in water?

Step-by-step solution

To determine the speed of light in a specific medium like water, we need a laboratory method where the required path length of light is relatively small, so that a tube filled with water can be placed in the optical path. Roemer's method is an astronomical method based on the observation of the eclipses of Jupiter's moons, so it cannot be used to measure the speed of light in water. Fizeau's method (using a toothed wheel) requires a very long path length (typically several kilometers). It is practically impossible
