WebIn a double slit experiment the angular width of a fringe is found to be 0.2∘ on a screeen 1 m away. The wavelength of light used is 6000 A. What will be the angular width of a fringe if the entire experimental arrangement is immersed in water? Refractive index of water =4/3.A. 0.15∘B. 0.18∘C. 0.2∘D. 0.27∘ WebJan 20, 2024 · The fringe width is given by X = λD/d For first case X 1 = λD 1 /d ………….. (1) For second case, X 2 = λD 2 /d ………….. (2) Dividing equation (2) by (1) X 2 / X 1 = (λD 2 /d) x (d/ λD 1) ∴ X 2 / X 1 = D 2 /D 1 ∴ X 2 = (D 2 /D 1) x X 1 ∴ X 2 = (2/1.5) x 6 = 8 mm

WebThe fringe width is the distance between two consecutive bright (or dark) fringes. β = λD/d The fringe width is dependent on the distance between the slit and the screen, whereas the angular fringe width is independent. θ= λ/d Here θ gives the smallest possible angle between two point sources. = β/D Angular width doesn’t depend on the number “n”. WebSep 12, 2024 · The plot shows the expected result for a slit width a = 2λ and slit separation d = 6λ. The maximum of m = ± 3 order for the interference is missing because the minimum of the diffraction occurs in the same direction. Example 4.4.1: Intensity of the Fringes
WebAngular fringe width is given by: tanθ≈θ= Dβ= dλ Example: In Young's double slit experiment the two slits are illuminated by light of wavelength 5890 ∘A and the distance between the fringes obtained on the screen is 0.2 ∘. If the whole apparatus is immersed in water then find the angular fringe width. (refractive index of water is 4/3) Solution: WebApr 6, 2024 · The angular distance between the two first order minima (on either side of the center) is called the angular width of central maximum, given by 2 θ = 2 λ a The linear width is as follows, Δ = L.2 θ = 2 L λ a The width of the central maximum in the diffraction formula is inversely proportional to the slit width.
Weby n m a x = n λ D d Similarly the nth order of minimum occurs at a distance from the central maximum given by, y n m i n = ( 2 n − 1) λ D 2 d where n = 1, 2, ……….. Therefore the fringe width β, defined as the distance between two consecutive maxima (or consecutive minima) can be obtained β = n λ D d − ( n − 1) λ D d = λ D d β = λ D d WebIn the YDSE conducted with white light (4000Å-7000Å), consider two points P 1 and P 2 on the screen at y 1 =0.2mm and y 2 =1.6mm, respectively.
