Homework Help: Types of waves

  1. Mar 1, 2009 #1
    1. The problem statement, all variables and given/known data

    The speed of surface waves in water decreases as the water becomes shallower.Suppose waves travel across the surface of a lake with a speed of 2.0m/s and a wavelength of 1.5m. When these waves move into shallower part of the lake, their speed decreases to 1.6m/s, though their frequency remains the same. Find the wavelength of the waves in the shallower water.

    2. Relevant equations

    3. The attempt
