SUMMARY
The double-slit experiment demonstrates that the interference pattern is influenced by both the width of the slits and their spacing. As the slit width increases, the diffraction pattern changes, affecting the visibility and spacing of the interference fringes. The relationship between fringe width (w), slit separation (s), and screen distance (D) is defined by the formula w = (λ/s) D, where λ represents the wavelength. This indicates a direct correlation between the slit parameters and the resulting interference pattern, which can be explored using simulations and classical wave mechanics principles.
