. A stone tossed into a pond makes ripples starting at the place it hits the water that lasts for 8.0 s. The speed of surface waves is 30 cm/s. a. (5 pts) Over what distance on the surface of the water does the group of waves extend? b. (5 pts) The wave lasts for 12 wave crests. Using the same criterion as in the discussion above Eq. (4.4), estimate the precision with which the wavelength can be determined.
