In the double-slit experiment, the behavior of accelerated objects, such as electrons or particles, is governed by the principles of quantum mechanics. When these particles are accelerated towards the double-slit apparatus, they exhibit wave-particle duality and can interfere with themselves, leading to an interference pattern on the screen placed behind the slits.
The interference pattern consists of a series of bright and dark fringes. The bright fringes correspond to regions of constructive interference, where the waves from the two slits reinforce each other. The dark fringes, on the other hand, represent regions of destructive interference, where the waves from the two slits cancel each other out.
The position of the bright and dark fringes on the screen depends on the wavelength of the particles and the geometry of the double-slit setup. The interference pattern is typically observed as a series of alternating bright and dark bands that extend beyond the region directly behind the material between the two slits.
Therefore, the accelerated objects do not hit the screen at the spot just behind the material between the two slits. Instead, the interference pattern appears on the screen, exhibiting a distribution of bright and dark fringes that extend across the entire screen.
It's worth noting that the exact positioning of the interference pattern depends on various factors, including the distance between the slits, the distance between the slits and the screen, and the properties of the particles used. The interference pattern can be calculated and predicted using mathematical formalisms, such as wavefunctions and diffraction principles, which describe the behavior of the particles as both waves and particles.
