Loudness of sound depends on amplitude of vibrations | Sound | Physics

Показать описание
In this activity, we learn how loudness of sound is related to the amplitude of vibrations. We fill a steel glass with some water and then strike the rim of the glass with a spoon . We do this many times, increasing the hardness with which the spoon is hit every time. We observe that each time the sound produced is louder. Then we place a light polystyrene ball close to the glass as shown in the video and repeat the earlier step. We see that each time the ball jumps a little farther from the glass. This tells us that as the amplitude of vibrations gets larger, the sound produced becomes louder.

Loudness also depends on area of the vibrating object, medium and distance from the source .

Btw loved the practical sir ✨

Mean more amplitude more will be the loudness
