In the above figure, which shows the pattern of interference fringes for light of wavelength 485 nm passing through two narrow slits, projected onto a screen a distance of 1.81 m away. The distance on the screen between the centers of two adjacent bright fringes is 1.66 cm. What is the distance between the two slits?

In a double-slit experiment coherent light of wavelength 652 nm is incident upon two slits that are separated by 0.425 mm. The fringe pattern is viewed on a screen that is 1.69 m away. What is the distance on the screen between the first-order and second-order bright fringes? Give your answer in cm.

Light of wavelength 680 nm falls on two slits and produces an interference pattern in which the fourth-order fringe is 0.038 m from the central fringe on a screen 1.0 m away. What is the separation of the two slits

Two slits space 0.580 mm apart are placed 72.0 cm from a screen. What is the distance between the second and third dark lines of the interference pattern on the screen when the slits are illuminated with coherent light with a wavelength of 500 nm?

The figure shows a double slit located a distance x = 3.15 m from a screen, with the distance from the center of the screen to a bright fringe given by y. When the distance d between the slits is large compared to the wavelength λ, there will be numerous such bright fringes.  Calculate the distance between adjacent fringes, in centimeters, for 640-nm light falling on double slits separated by 0.0785 mm. You may assume that θ is small.

Light with a wavelength of λ = 605 nm is incident on a single slit of width w = 2.25 micrometers. A screen is located L = 0.65 m behind the slit and an interference pattern has formed on it. a) What is the distance between the central bright spot and the first dark fringe, D, in meters?

Two slits, 0.5 mm apart are placed at a distance of 1.5 meters from a screen. Light of 300nm illuminates the two slits and an interference pattern is observed on the screen. What is the distance between the central bright spot and the first bright spot on either side?

Green light has a wavelength of approximately 510 nm. When green light is diffracted through a single slit with a width of 30 mm, the observed separation of the first dark fringe and the central maximum is 3.6 cm. Determine the distance between the slit and the screen for this observation to have been made
