Now, tie a sturdy piece of string (a shoe string should work fine) to the end of your tuning fork. Strike the tuning fork, then immediately swing it around at the end of the string in a vertical circular pattern beside you. In other words, the tuning fork should be swinging in a circle beside you, down toward your feet then up toward your head and repeating. Somehow, record an image of the swinging tuning fork to submit with the lab document. Strike the tuning fork very hard once again, and swing the oscillating tuning fork around in the vertical circle at a slow speed and also at a fast speed. Below, describe what you should observe about pitch (not loudness) in each situation. Then, if you do not notice what you expect, provide reasons why it is not what you expect (respond before moving on to Conclusions)
