In this experiment you will be adjusting the length of string of a pendulum until you get a pendulum that has a frequency of .5 Hz, 1 Hz and 2 Hz. Remember, a Hz is one vibration (or in this case swing) per second. So .5 Hz would be half a swing per second (swing one way but not back to the start). 1 Hz would be one full swing per second. Lastly, 2 Hz would be two swings per second. A swing is the same as a vibration so the pendulum must move away from where you dropped it and then swing back to where it began for it to be one full swing/vibration.

I’m not getting 31.5m either.
Wavelength would be speed divided by frequency. The speed is 5 m/s and the frequency is .158 Hz.
So that would formula would be 5 ÷ 0.158 That comes out to 31.65. I think we have a typo in there, so sorry about that! I’ll get it fixed.
Hi, I have a question about answer for Frequency. Answer given on # 3 lesson 6 .( 31.5m ) I am not able to come up with this answer. Please show me how this is done.
Thank you.
