1. Review Concept: PS-7.4 Use the formulas v = f λ and v = d/t to solve problems related to the velocity of waves.

2. The diagram below shows a wave on a Slinky spring. The velocity of the wave is 1.5m/s. A.What type of wave is this? B.Express the wavelength in meters. C.What is the frequency of the wave?

3. The diagram below shows a wave on a Slinky spring. The velocity of the wave is 1.5m/s. A.What type of wave is this? Longitudinal (or Compression wave) B. Express the wavelength in meters..32m C.What is the frequency of the wave? V=f λ so f= v/ λ f= 1.5m/s. f= 1.5m/s.32m f= 4.7hz
