Water waves of wavelength $\lambda $ are incident normally on an obstacle with a narrow gap. The width of the gap is equal to $\lambda $. The waves from the gap emerge over an angle $\theta $, as shown.
The gap is slowly widened.
Which changes, if any, occur to $\theta $ and to the wavelength of the emerging waves?
