To fill in the blanks, we need to understand the relationship between the amplitude of vibration and the loudness of the sound produced by a violin string when it is plucked with different strengths. 1. **First Blank**: If a violin string is plucked strongly, its amplitude of vibration __________ (increases/decreases). - When the string is plucked strongly, it vibrates with greater energy, leading to a larger displacement from its mean position. This means that the amplitude of vibration **increases**. 2. **Second Blank**: The note heard is __________ (louder/softer). - Since the amplitude of vibration has increased, the loudness of the sound produced also increases. Therefore, the note heard is **louder**. ...
