उत्तर
- The frequency of sound emitted due to vibration in an air column depends on the length of the air column.
- The factor which influences the frequency of sound is the length of the air column. As the length of the air column increases, the frequency decreases. Thus, we can conclude that they are inversely proportional to each other. `"f" alpha "l"/iota`
