Due to superposition principle.
What is it?
When two or more waves traverse in a medium, they travel as if the other waves were absent. What does it mean?
In case of marbles moving across if they come into contact they would collide and change it path. But as the waves meet together no such material collision and no change in the direction of their motion. Hence that valid statement as the first part of superposition principle.
Now second part is for the interference part. Though there is no collision, but at a particular point in the medium the displacement of the particle in the medium is the resultant of the displacements produced by all the waves at the instant. So if the resultant displacement is minimum then it is termed as destructive interference and if the displacement is maximum then it is considered as the constructive interference.

Constructive interference causes wave amplitude to become larger because when the peaks of two waves align, they add together. Destructive interference, on the other hand, causes the amplitude to decrease when peaks align with troughs and cancel each other out.
Destructive interference causes the crest of a wave to decrease or cancel out. This occurs when the crest of one wave aligns with the trough of another wave, resulting in a reduction or cancellation of the overall amplitude.
EMI
Destructive interference of the waves due to poor design of the building.
This process is called destructive interference. This occurs when two waves collide, where one is in a trough and one is in a crest. If the waves are both a max amplitude, max crest and max trough, there will be complete destructive interference.
electrical interference
Constructive interference can be a confusing concept when called interference. It is wave interference that is moving in phase with another wave. This causes the waves to for a resultant wave with a greater amplitude. Destructive interference is wave interference that is moving out of phase with another wave. These waves form a resultant wave of lower amplitude.
The appearance of white moving spots in a video is typically caused by digital noise or interference in the recording or playback process. This can be due to issues with the camera sensor, poor lighting conditions, or problems with the video encoding or decoding process.
