water waves in a ripple tank are diffracted by a narrow aperture.if the wavelength of the water waves is decreased slightly whilst keeping the aperture size the same ,which one of the following will happen?

the waves will spread out more
the waves will spread out less
the amount of diffraction will be the same
diffraction will stop

As the wavelength decreases, the spreading of the wave at the edges of the aperture also diminishes =>
the waves will spread out less
the waves will spread out less
