plucking the rubberband by your hand can produce sound,beating the plate with the use of spoon,playing guitar,when honey bee or any other insect wave thier wings sound produced,take a 4 glass with full of water in it and start beating with spoon in each glass it may produced different sound and don't forget to pour different level of water in all the four glasses then it will make much better sound..........
b)
We know that sound is produced due to vibrations of a body. When a body starts vibrating,the particles of the medium around it also start vibrating,when these vibrating particles come in contact with other particles they too start vibrating. In this way vibrations are transferred from source to our ears as sound energy is passed through the vibrations.
