To produce interference fringe pattern, draw a ray diagram of Young's double slit experiment. Derive an expression of fringe width for bright interference fringes. If fringe width of bright fringes is 2 m m, write the fringe width for dark fringes. Whether the center point of interference fringe pattern is bright or dark? Explain it.
If d becomes much larger than X, the fringe width will be very small. The maxima and minima, in this case, will be so closely spaced that it will look like a uniform intensity pattern. This is an example of the general result that the wave effects are difficult to observe if the wavelength is small compared to the dimensions of the obstructions or openings to the incident wavefront.
Jun 20, 2024 · The light intensity that the slits produce keeps on increasing with the increased width of the slit. Therefore, the screen develops a brighter fringe with an increase in the slit width. Coloured fringes are then created on the screen if we replace the monochromatic light with the white light. Fringe width is denoted as β, which is equal to μD ...
In Young's double slit experiment, fringes of certain width are produced on the screen kept at a certain distance from the slits. When the screen is moved away from the slits by 0.1 m, fringe width increase by 6 × 10 − 5 m. The separation between the slits is 1 mm. Calculate the wavelength of the light used.
In Youngs double slit experiment, the fringe width is β. If the entire arrangement is now placed inside a liquid of refractive index μ, the fringe width will become. View Solution.

According to fringe width formula, the fringe width is directly proportional to the wavelength of light used. As the wavelength of red light is more than that of blue light. So fringe width in case of red light is more than that for the blue light. Thus fringe width increases when we replace the blue light with red light. Hence option 1 is correct.
Jan 28, 2015 · Fringe width is the distance between two successive bright fringes or two successive dark fringes. In the interference pattern, the fringe width is constant for all the fringes. It means all the bright fringes as well as the dark fringes are equally spaced. We can derive the equation for the fringe width as shown below.
