in the double slit experiment , why must the two slits be at the same distance from the first slit?should the interfering waves have the same phase and why?

but coherence doesn't mean they have the same phaseTo do the experiment using non-laser light you need to get over the poor coherence of the light. Making the paths as symmetrical as possible will give the best pattern (one with the best defined peaks and nulls).

I read before that Coherence means that the phase difference is constant over time
The double slit experiment is a classic experiment in quantum mechanics that demonstrates the wave-particle duality of light and matter. It involves shining a beam of particles (such as electrons or photons) through two parallel slits and observing the resulting interference pattern on a screen.
The double slit experiment is important because it challenges our understanding of the nature of reality and the behavior of particles at a subatomic level. It has also led to the development of new theories and models in physics, such as quantum mechanics.
The interference pattern observed in the double slit experiment is significant because it shows that particles can behave like waves, which was previously thought to only apply to light. This demonstrates the wave-particle duality of matter, which is a fundamental concept in quantum mechanics.
Some interpretations of the double slit experiment, such as the Many-Worlds interpretation, suggest that each possible outcome of the experiment exists in a parallel universe. This is based on the idea that particles can exist in multiple states simultaneously, and the interference pattern is created by the interaction of these different states.
The double slit experiment has been used in various fields, such as medicine and engineering, to better understand the behavior of particles and develop new technologies. It has also been used to study the properties of materials and improve our understanding of the universe at a subatomic level.
