Explain why, if we strike a table lightly, we hear a soft sound but if we hit the table hard, a loud sound is heard.
The table top viberates with a less amplitude when we strike it lightly. This lead to produce a soft sound because the energy supplied to the top of the table is low, so the amplitude is low. But on the other hand when we strike the tabe very hard then the energy supplied to the table is very high, this makes the top of the table to viberate rapidely and hence a loud sound is heard.
