Why is the velocity of light in vacuum considered a constant?

Because it is a fundamental physical constant defined exactly as 299,792,458 metres per second, serving as the ultimate speed limit for information and matter transfer in special relativity.

Does the velocity of sound in pure water remain the same under all conditions?

No, it depends mainly on temperature, pressure, and salinity, so it varies with environmental conditions.

What is the main purpose of converting from velocity of light in vacuum to velocity of sound in pure water?

To compare propagation speeds for electromagnetic and acoustic signals, which is important for timing synchronization and interpreting travel times in various scientific and engineering fields.
