In this question, we are given two snapshot graphs.
00:07
Two snapshot graphs are taken at 10 milliseconds apart.
00:13
So there's a blue curve, there's also a red curve, which i'm not able to draw perfectly on the diagram.
00:21
So just an illustration.
00:25
Then there's also a so another curve, green curve looks something like this.
00:35
Yeah.
00:36
So in this question we want to find the wavelength, speed, frequency, and the amplitude of the wave.
00:46
Okay, so based on the snapshot graph, we can read off the wavelength to be 12 cm and then the frequency or the speed.
01:06
Okay, the speed is just distance derived by time.
01:12
The distance is, i kind of use ruler to measure the distance.
01:21
It's a bit hard to kind of describe over here.
01:30
So you should be, if you measure the distance, you should be getting something like 2 .5, you are by 2 .3...
