Why is it something
no sound never stops traveling!
Our ears are designed to hear sounds traveling through air. When these sounds are made underwater, they travel at slower speeds, causing them to bounce off surfaces differently and sound differently.
When something is traveling at the speed of sound, 343 m/s, it is said to be traveling at mach 1. When traveling at twice the speed of sound it is traveling at mach 2 and so on. Wikipedia.org, 'The World's Encyclopedia' has an entire article on Mack Number. Refer to the related link in the Related Links section below.
Sound travels in water as a longitudinal wave.
340m/s
The speed of sound is only 768mph.
Sound can travel through any state of matter, including solids, liquids, and gases. The speed of sound can vary depending on the medium it is traveling through, with sound traveling fastest through solids and slowest through gases.

almost instantly.
It depends on the substance the sound is traveling through. If the sound is traveling through air, it is usually about 800km/h. If it is traveling through water, the speed is about 4000km/h. If it is traveling through cosmos, its speed is 0km/h.
Close! Actually, Mach-1 is the speed of sound. anything above Mach-1 (Mach-(1-5)) is supersonic, all the way up to Mach-5, at which point an object is called "Hypersonic". Sometimes speeds above Mach-10 are referred to as "High-Hypersonic". So, a jet moving at Mach-1 wouldn't actually be traveling FASTER than sound, it would be traveling AS FAST as sound.
Only if it's traveling at less than the speed of sound
