Final answer:
When sound waves reach a sheet of paper, they cause the paper to vibrate and move in response. This happens because the vibrations in the air transfer energy to the paper. The intensity of the sound affects the degree of movement in the paper.
Step-by-step explanation:
The movement of the sheet of paper when blown gently or when exposed to sound waves illustrates how vibrations or oscillations can create sound and cause objects to move.
When you speak softly, the vibrations produced by your vocal cords hit the edge of the paper and cause it to move slightly.
When you speak louder, the vibrations become stronger and the paper moves more noticeably.
This happens because sound is created when an object vibrates, such as the air molecules produced by your voice. These vibrations travel as waves through the air, and when they reach the paper, they cause the paper to vibrate in response.
The paper then moves in the same pattern as the sound waves, which is why it may move more or less depending on the intensity of the sound.
This movement of the paper is an example of the transfer of energy from the sound waves to the paper.
The vibrations produced by the sound waves transfer energy to the paper, causing it to move.
This shows how energy can be transferred through vibrations and how it can cause objects to move.
