Hey all,
       In class we did some experiment in which we took a 370cm rope, with a person on each end. We than swung it like a jump rope which would make a half of a wav, we than counted the frequency, and time, and configured the wave length to be 740cm.  We continued this for 1 wave,1.5 wave, 2 waves and so on with each time the rope having to be swung faster in order to have a larger number of waves. In a post lab question they call our rope a stretched spring.  They are asking, what does the spring have to do with electromagnetic energy? I don't understand how I'm suppose to answer that question.


Also another question.  It reads....
If your diagram represents a wave being generated with a spring like the one used in the experiment, and it took 25 seconds to generate 60 of these wave forms, what is the frequency of the wave? Show calculations.
                         I have no idea how to set this up. But some how in class i guessed that it would be 60/25 = 2.4 hz , but i doubt that is correct as i dont even understand how i came up with that.

Sounds more like physics to me.

Well its a chemsitry class, can anyone help me out??

Well, electromagnetic energy travels in waves.

That looks ok to me.  The frequency of something is how many cycles per second.  So if each cycle generates a waveform, then you had 60 cycles per 25 seconds or 2.4 cycles per second.

Okay. Thank you very much Ygg, I appreciate it.
