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