What will be the effect on fringe width when distance between Young double slits become doubled?

Fringe width y=λD2d ,2d = separation between the slits D = distance between screen and slits λ=wavelength of incident light wave. Hence fringe width will become 4 times the earlier width.

How does the fringe width of interference changes when the distance between screen and two sources increased?

) has a direct dependence on D, fringe width decreases if the distance between the slits and screen is decreased. ) of the source is increased because, fringe width and frequency have inversely dependent on each other.

How does fringe width of interference fringes change?

Fringe width, β = Dλ/d => β ∝ λ for same D and d. When the whole apparatus is immersed in a transparent liquid of refractive index n =1×3, the wavelength decreases to λ = λ/n = λ/1.3. so, fringe width decreases to 1/1.3 time.

How does slit width affect fringes?

The separation of the interference fringes depends on the slit separation. If now the slit width is increased the width of the diffraction envelope is decreased whilst the separation of the interference fringes stays the same. So less interference fringes will be visible.

How does the double-slit pattern change when the slit width is increased?

As the number of slits increased, the fringe width would also increase, because with more slits, the more slits the light waves could travel through, and more interference could occur.

How does the fringe width change in young’s double-slit experiment?

How does the fringe width, in Young’s double-slit experiment change when the distance of separation between the slits and screen is doubled? where all the symbols have their usual meanings. Thus fringe width gets also doubled. Was this answer helpful?

What happens if the fringe width of a double slit is doubled?

Fringe width is inversely proportional to spacing between slits. If it doubled then fringe width will be halved. What is bright and dark fringe in Young’s double slit experiment?

How to use a double slit interference pattern?

Using two slits of this width whilst keeping the slit separation (centre to centre) the same as before results in this interference pattern. So you will note that the slit widths control the modulation of the intensity of the double slit interference pattern. The slit separation controls the separation of the interference fringes.

What is the diffraction pattern in the double-slit experiment?

The diffraction pattern in the double-slit experiment is the convolution of the single-slit result with delta functions indicating the placement of the slits. Have fun doing the deconvolution of the observed fringe pattern in order to fit the result with Fraunhofer theory.
