5. A swimming pool pump generates 10 water waves every 15 s. a. Determine the frequency of the waves. b. If the wave crests are separated by 2.0 m, determine the speed of the waves. c. Predict what will happen as two wave crests interfere near the middle of the pool. 6. Green light has a frequency of 5.70 x 10" Hz. Use the universal wave equation to calculate the wavelength, in nanometres, of green light. The speed of light in a vacuum is 3.00 x 10 m/s.
