To solve the question about how to lower the frequency of vibrations of a blade fixed at one end, we can follow these steps: ### Step-by-Step Solution: 1. **Understanding the System**: - The blade is fixed at one end (let's call this point A) and free at the other end (point B). When you press and release the free end, the blade vibrates, producing sound. 2. **Frequency of Vibration**: ...
