From the question we are told that:
Far point is
Near point is
Therefore
Focal Length
Generally the equation for the Lens is mathematically given by
The frequency of a wave is the number of complete oscillations passing a given point per second.
In this case, assuming the duck is stationary, we have 4 complete waves passing the duck in one second: therefore, the frequency of the wave is
