What is the wavelength of waves in shallower water?

[newfie88]

Homework Statement

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.

Homework Equations

3. The attempt
(2.0m/s-1.6m/s)/1.5=.26667

newfie look at the equation linking speed frequency and wavelength.
