Answer 1

Answer:

A fork consists of two tines and a handle. When it is hit with rubber hammer, the two tines starts vibrating. The back and forth motion of tines produces disturbances in the surrounding air molecules. As the tines extend outward from their original position, they compress surrounding air molecules which results in the creation of high-pressure region close to the tine. When the tine moves inwards, it produces a low pressure region near the tine. With more vibrations of tine, an alternating pattern of high and low pressure regions are created. These pressure difference regions help in propagation of sound waves from one location to another.
