Light is faster than sound.
Light travels almost a million times faster in air. There is very little difference between the speed of light in a vacuum as in air. It is around 0.01% slower in air. Because of the difference between the speed of light and sound you can estimate the distance of a lightning strike. For every 3 seconds between the flash and the sound of thunder the lightning strike is 1 km away or 5 seconds for a mile. The actual speeds are light 300,000 km per second speed of sound 0.33 km per second.
Speed of sound in water is approximately 1500 meters per second. ( The exact speed depends on the depth of water and its density) and the speed of sound in air is approximately 340 meters per second. So sound is almost 4.4 times faster in water than in air.
No. In general, the denser the medium, the faster sound travels.
It is different because sound vibrates and light reflects
