Question

what is sound how does it produce how does it travel in different medium

Answer 1

sound-vibrations that travel through the air or another medium and can be heard when they reach a person's or animal's ear.The vibrating body causes the medium (water, air, etc.) around it to vibrate. Vibrations in air are called traveling longitudinal waves, which we can hear.The sound waves move through each of these mediums by vibrating the molecules in the matter. The molecules in solids are packed very tightly. Liquids are not packed as tightly. And gases are very loosely packed. This enables sound to travel much faster through a solid than a gas. Sound travels about four times faster and farther in water than it does in air. Approx speed of sound in air is 343 m / s.
