An enthusiastic physics student enjoyed the opportunity to collect data from standing waves in a spring. She and her partner held the ends of their spring 4.00 meters apart. There were 5 nodes in the standing wave produced. She moved her hand from the rest position back and forth along the floor 20 times in 4.00 s. Sketch the situation and determine the following: the wavelength of the wave the student sent.
what's the wavelength of the wave the student sent
