Double slit interference occurs when a single light wave passes through two narrow, parallel slits, resulting in an interference pattern. Single slit interference occurs when a single light wave passes through a single narrow slit, resulting in diffraction.
The distance between the slits affects the spacing of the interference pattern. As the distance between the slits increases, the spacing between the bright and dark fringes decreases.
The distance between the slits and the screen affects the size of the interference pattern. As the distance increases, the interference pattern becomes larger and less defined.
The wavelength of the light wave affects the spacing of the interference pattern. As the wavelength increases, the spacing between the bright and dark fringes also increases.
The intensity of light affects the brightness of the interference pattern. Higher intensity light will result in a brighter interference pattern, while lower intensity light will result in a dimmer interference pattern.
