Question

what is sound an
how it is produced

Answer 1

sound is vibrations that travel through the air and can be heard by person's or animals ears. sound is produced when something vibrates. the vibrating body causes the medium (water, air) around it to vibrate.

Answer 2

sound is a form of energy. the sound is a form of that energy which makes us hear...sound is produced by vibration of objects.eg- we can hear a sound when stretched rubber band vibrates. sound needs a medium to travel. sound cannot travel in vacuum. sound travels best in solids because the molecules in solods are colse to each other so passing the vibration will be more faster and easier in it.
