Do interacting waves give rise to diffraction patterns?

Yes. The destructive and constructive interference of waves creates the diffraction patterns like those seen in the double slit experiment.

To add on, constructive interference is when wave peaks coincide, and the overall wave amplitude increases. Destructive interference is when a trough coincides with a peak, and the overall wave amplitude decreases. Because the double slit experiment gives rise to diffraction patterns, it demonstrates the wave-like properties of light.

what is the difference between constructive and destructive interference?

constructive interference is when two waves interacting with one another are in phase with one another. So, when the waves interact the amplitude of the waves add together. Destructive interference, on the other hand, is when the waves are out of phases, so when they interact with one another, the waves will "cancel" each other out and decrease the amplitude of the wave.

Do the different types of wave interaction create different diffraction patterns or do they all result in the same pattern?
