Violin the music teacher is hurriedly approaching the scene of the open air concert. His student, Tom has just finished tuning the “A” string of his guitar. Arriving at the scene Violin asks Tom to retune the string, because the frequency meter he has measured a
frequency of 445 Hz. Tom says that he tuned the string correctly to note “A” having a frequency of 440Hz. |

 |
 |
|||
| 1. No, because Tom was not moving, so the frequency of the sound created by the string could not change | ||||
| 2. Yes, if Violin was coming closer at a rather high speed, because then he measures a higher frequency. | ||||
 | 3. No, because the teacher is always right! | |||
