What are the possible frequencies of our string? so we're given the beats is four beats per second, and we have our beat frequency.
00:12
Now, our highest frequency, so given our, given our beats per second, then to solve this problem, what we want to do is we'd like to find our frequency.
00:34
So what we're going to do is we're going to take our beats per second.
00:37
And we're going to add or subtract them.
00:40
So for our higher frequency, we have 523 plus 4 beats per second.
00:45
So 523 plus 4 beats per second is 527 hertz for a higher frequency.
00:52
For a lower frequency, we do our 523 minus 4 beats per second.
00:57
And that should be 519 hertz.
01:01
So that's going to be our lower frequency value...
