Light of wavelength 680 nm falls on two slits andproduces an interference pattern in which the third-orderbright red fringe is 38 mm from the central fringe on a screen2.8 m away. What is the separation of 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.

A laser light with wavelength of, N = 630nm, allowed to pass through double slit interference with a separation distance of, d= 0.03mm. The distance between the slits and the board is x-1.5 meter: What is the distance in cm for the fourth bright maxima, ÿ4 from center of the screen?

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 two most prominent wavelengths in the light emitted by a hydrogen discharge lamp are 656 nm (red) and 486 nm (blue). Light from a hydrogen lamp illuminates a diffraction grating with 460 lines/mm, and the light is observed on a screen 1.50 m behind the grating. What is the distance between the first-order red and blue fringes?

In a double-slit experiment, coherent light of wavelength 545 nm is incident upon two slits that are separated by 0.434 mm. The fringe pattern is viewed on a screen that is 2.32 m away. What is the width of the central maximum on the screen? Give your answer in cm.

In a Young's double-slit experiment, a set of parallel slits with a separation of 0.106 mm is illuminated by light having a wavelength of 587 nm and the interference pattern observed on a screen 3.50 m from the slits. (a) What is the difference in path lengths from the two slits to the location of a fifth order bright fringe on the screen? 2.935 um (b) What is the difference in path lengths from the two slits to the location of the fifth dark fringe on the screen, away from the center of the pattern? 3.228e-6 Your response differs significantly from the correct answer.
