Is this file broken?

Hi folks,

 

I found this flash file as I was trying to visualize frequency. The more I increase the frequency, the longer the waveform gets. How is this possible? Shouldn't the wave get smaller and smaller as the frequency gets higher and higher?

 

I'm talking about the second file on the page. It it broken? How is it possible that as I increase the frequency of the dial, the frequency declines....?

I hope it's OK that I posted a link to another site, I just don't know how to import Flash onto here. As you can see, the post is from 2006, so I'm not trying to advertise anything!

 

 

Thanks!

Maybe it is using seconds/cycle instead of cycles per second?

The control definitely says "frequency in Hz" and in an oscilloscope the X trace travels across the tube face at a given speed. Thus the trace lenth indicates time. Under the circumstances I am sure the program is faulty.
