“Sound travels in the form of waves”. Justify your argument.

1.	“Sound travels in the form of waves”. Justify your argument.
Answer» 1. Sound is a form of energy which travels through the air and reaches our ears to give the sensation of sound. 2. There may be two possible ways by which transfer of energy from the source of sound to our ears take place. a) Source of sound produces disturbances in air and they strike our ears. b) Some particles are shot off from the source of sound and they reach our ears. 3. If the second explanation is correct, the vibrating body would gradually lose its weight as particles are continuously shot off from it. 4. This is impossible because it would lead to vanishing of the object. 5. Hence the first explanation that the sound travels through disturbances in the form of waves is correct.

Answer»

1. Sound is a form of energy which travels through the air and reaches our ears to give the sensation of sound.

2. There may be two possible ways by which transfer of energy from the source of sound to our ears take place.

a) Source of sound produces disturbances in air and they strike our ears.

b) Some particles are shot off from the source of sound and they reach our ears.

3. If the second explanation is correct, the vibrating body would gradually lose its weight as particles are continuously shot off from it.

4. This is impossible because it would lead to vanishing of the object.

5. Hence the first explanation that the sound travels through disturbances in the form of waves is correct.
