@@ -24,7 +24,7 @@ The Hz number is the frequency of the pitch you're hearing.
 The higher the frequency, the higher the pitch and vice versa.
 A pitch occurs whenever something is vibrating / oscillating at a frequency, in this case it's your speaker.
 The unit **Hz** describes how many times that oscillation happens per second.
-Our eyes are too slow to actually see the oscillation on the speaker, but we can [see it in slow motion](https://www.youtube.com/watch?v=CDMBWw7OuJQ&t=5s).
