Question

Describe 2 experiments to show that sound has vibrations associated with it

Answer 1

Answer:

The two experiments which show that sound has vibrations associated with it are:  

                             Aluminium Hanger Experiment

         Tie a rubber band to an aluminium hanger and make a bow - like structure. When the elastic rubber band is pulled, a sound can be heard. This is because the vibrations of the string produce the sound.

          If the string is stopped in between then the sound ceases. By placing a v-shaped paper strip on the elastic band, the vibrations can also be visually seen.  

                                    Tuning Fork Experiment

         The tuning fork experiment is a simple experiment that proves sound has vibrations. When the prongs of the tuning fork are made to vibrate by hitting, the sound is produced.

         If the prongs hit a harder surface, then the vibrations are more and the sound produced is more. With a softer surface, the prongs produce lesser vibrations and no or less sound is produced with it.
