The interference pattern on a screen of a monochromatic light (A=549 nm) passing through two very narrow slits with separation 0.732 mm is observed. Find the width (in mm) of the central interference maximum if the screen is 8.1 m away from the slit. Round your answer to 2 decimal places.

A hydrogen gas discharge lamp is used as a coherent light source illuminating NN slits in a barrier with a slit separation of 28 μmμm. The interference pattern is projected on a screen 2.00 m from the barrier. The first-order principal maxima to one side of the central maximum. The number of slits is sufficiently large that the individual lines are sharp and widely separated. Note that there are four different colors appearing in the source, violet is the color closest to the central maximum. λ=656λ=656 nm (red) λ=486λ=486 nm (cyan) λ=434λ=434 nm (blue-violet) λ=410λ=410 nm (violet) The blue-violet line is thin and somewhat faint, and it may be difficult to see without enlarging the figure. When viewing multiple orders of the interference pattern, the color sequence may change due to the interleaving of the different orders. 1. Using the values given in the problem statement, what is the distance along the screen, in centimeters, from the the central maximum to the first line?  2.…

When blue light of wavelength 470 nm falls on a single slit, the first dark bands on either side of center are separated by 51.0⁰. Determine the width of the slit. Express your answer to three significant figures and include the appropriate units. μA D= Value Units ?

The wavelengths of the visible spectrum are approximately 400nm (violet) to 700nm (red). Find the angular width of the first-order visible spectrum produced by a transmission diffraction grating with 433 lines per millimeter when white light falls normally on the grating.Give your answer in degrees.

Light of wavelength 613.0 nm is incident on a narrow slit. The diffraction pattern is viewed on a screen 81.5 cm from the slit. The distance on the screen between the fourth order minimum and the central maximum is 1.91 cm. What is the width ?a of the slit in micrometers (μm)?

Light of wavelength 588.2 nm illuminates a slit of width 0.63 mm. (a) At what distance from the slit should a screen be placed if the first minimum in the diffraction pattern is to be 0.86 mm from the central maximum? (b) Calculate the width of the central maximum. Step 1 (a) As shown in the figure, dark bands or minima occur where sin 0 = m(2/a). For the first minimum, m = 1 and the distance from the center of the central maximum to the first minimum is y₁ = L tan 8, where L is the distance of the viewing screen from the slit. 32 sin dark = 22/a 31 sin dark = λ/a HE 0 -1 sin dark = -λ/a -2 sin dark = -22/a Viewing screen a Because is very small, we can use the approximation tan sin 0 = m(2/a). Substituting the approximation and solving for the distance to the screen, we have 6.3 x 10 m ³ m ) (₁ L = = y ₁ ( ² ) = x 10-3 m x 10-⁹ m m.

Using monochromatic light, an interference pattern is generated on a screen 50.0 cm away from a double slit. The width of the slit is 12 μm.  The third dark fringe is 6.0 cm from the center of the central maximum. What is the wavelength of the light used in nanometres?

You illuminate a slit with a width of 78.1 µm with a light of wavelength 729 nm and observe the resulting diffraction pattern on a screen that is situated 2.27 m from the slit. What is the width w, in centimeters, of the pattern's central maximum? W = cm

The wavelengths of the visible spectrum are approximately 400nm (violet) to 700nm (red). Find the angular width of the first-order visible spectrum produced by a transmission diffraction grating with 433 lines per millimeter when white light falls normally on the grating.Give your answer in degrees.

Fringes in the Thomas Young experiment are produced using sodium light of wavelength 670 nm and two slits which are 1.2 mm apart. If the fringes are formed on a screen 0.8 m away from the slits, how far is the third order bright fringe from the middle of the screen? Give your answer in millimeters (mm).
