Progressive waves
 

Progressive waves problem 18


We observe a wave traveling to the right along a rope. At some point, an image of the wave is captured when the red sticker on the rope is on the crest of the wave as shown in the figure below.




  • Draw an image of this wave after 1/4 of the oscillation period.

  • Draw an image of the wave when it is shifted by 1.5 wavelengths.

  • How does the red sticker on the rope swing?
