All right, so looking at this graph, we have the displacement in centimeters over time as this thing goes around.
00:09
Now, to find the frequency, we first need to find the period of oscillation.
00:15
And so to do that, we can go crest to crest or trough to trough.
00:19
How long does it take for it to go one full progression? so it starts at negative 6 goes all the way to positive 6 and then back to negative 6.
00:29
So this time frame right here, this is the time it takes for one complete revolution, one complete trip to get back to its starting point.
00:39
And so we just need to take the difference between these two times, which this one looks to be right about in the middle.
00:46
So 0 .03 i put for that, 0 .03 seconds.
00:50
This one is slightly ahead of the middle, so i put that one as 0 .115, estimating that position right there.
00:58
And then we can find that the period is the difference between them.
01:03
So the period is this minus that or about 0 .085 seconds.
01:06
It's slightly more than that...
