2. The graph below represents the relationship be- tween wavelength and frequency of waves created by two students shaking the ends of a loose spring. Wavelength vs. Frequency 6.0 5.0 4.0 Wavelength (m) 3.0 2.0 1.0 0 0 1.0 2.0 3.0 4.0 5.0 6.0 Frequency (Hz) Calculate the speed of the waves generated in the spring.
