In a double slit, when the distance between the screen is NOT small (i.e. the rays r1 and r2 are not parallel) how is path length determined?
Thanks
Thanks
The path length in a double slit experiment is determined by measuring the distance between the two slits, known as the slit separation, and the distance between the slits and the screen where the interference pattern is observed, known as the slit-to-screen distance. These two distances are used to calculate the path length difference between the two waves passing through the slits.
Determining the path length in a double slit experiment is important because it allows us to understand and predict the interference pattern that will be observed on the screen. The path length difference affects the phase difference between the two waves, which in turn affects the intensity of the interference pattern.
The path length difference between the two waves passing through the slits determines the phase difference between them. This phase difference affects the intensity of the interference pattern observed on the screen. If the path length difference is an integer multiple of the wavelength, constructive interference occurs and bright fringes are observed. If the path length difference is a half-integer multiple of the wavelength, destructive interference occurs and dark fringes are observed.
Yes, the path length in a double slit experiment can be changed by adjusting the distances between the slits and the screen or by changing the wavelength of the light source. This can result in a different interference pattern being observed on the screen.
The path length in a double slit experiment is directly proportional to the wavelength of the light source. This means that as the wavelength increases, the path length difference between the two waves also increases, resulting in a larger phase difference and a different interference pattern being observed on the screen.
