"WebIn contrast, light waves can travel through a vacuum, and do not require a medium. In empty space, the wave does not dissipate (grow smaller) no matter how far it travels, because the wave is not interacting with anything else. This is why light from distant stars can travel through space for billions of light-years and still reach us on earth. " - How fast does light move in water

Why does light travel slower in water relative to vacuum?

WebSound moves at a faster speed in water (1500 meters/sec) than in air (about 340 meters/sec) because the mechanical properties of water differ from air. Temperature also affects the speed of sound (e.g. sound travels faster in warm water than in cold water) and is very influential in some parts of the ocean. WebHow Fast Is the Speed of Light in Air and Water? When astronomers gaze into the night skies, they are observing a mixture of real time, the recent past, and ancient history.
