Investigating Sound and Frequency
In conclusion, I found out that the shorter the length of air, the higher the frequency. I don't think I had any anomalies as none of the numbers really stood out. I think length would effect the sound because a long distance has a low pitch and vibrates slowly which make longer sound waves, a short distance has a high pitch and vibrates quickly making shorter sound waves. Therefore when a sound has shorter sound waves the frequency will be higher which means the pitch will also be higher.
In this practical, we could have worked a bit faster so we would have time to do the experiment three time in order to check our results instead of having to borrow some of other people's. Some errors that might have effected the results was the background noise since everyone was doing the practical at the same time some notes might have mixed together, making the frequency higher or lower than the actual note. I could improve this practical by doing it in a silent room with no background noise and just play the note to make sure I get a more accurate result.
