In a double-slit experiment the distance between slits is 5.8 mm and the slits are 0.83 m from the screen. Two interference patterns can be seen on the screen: one due to light of wavelength 430 nm, and the other due to light of wavelength 550 nm. What is the separation in meters on the screen between the m = 4 bright fringes of the two interference patterns? Number Units the tolerance is +/-5%

The width of a slit is 3.0 x 105 m. Light with a wavelength of 420 nm passes through this slit and falls on a screen that is located 0.65 m away. In the diffraction pattern, find the width of the bright fringe that is next to the central bright fringe. Second dark fringe First dark fringe Number Single slit Units Bright fringe- Bright fringe Central bright fringe First dark fringe Second dark fringe Screen

In a Young's double slit experiment the two slits are 0.037 mm apart and the screen is 2.48 m away from the slits. If the wavelength of the light used is 643 order bright fringe be located (in cm)? then how far away from the central bright fringe will the third nm,

In a single slit diffraction experiment, the width of the slit is 3.1 x 10-5 m and the distance from the slit to the screen is 2.2 m. If the beam of light of wavelength 600 nm passes through the slit and forms a diffraction pattern on the screen, what is the linear distance on the screen from the center of the diffraction pattern to the first dark fringe? 6.3 cm 7.4 cm 4.3 cm O 8.5 cm

In a Young's double-slit experiment, the angle that locates the second dark fringe on either side of the central bright fringe is 4.0 degrees. Find the ratio d/A of the slit separation d to the wavelength of the light. Number Units

In a single-slit diffraction pattern, the central fringe is 480 times as wide as the slit. The screen is 16,000 times farther from the slit than the slit is wide. What is the ratio X/W, where is the wavelength of the light shining through the slit and W is the width of the slit? Assume that the angle that locates a dark fringe on the screen is small, so that sin is approximately equal to tan (). Number Units

In the previous problem (Young's double slit experiment), given that D = 5 m, a = 0.25 cm and λ = 619 nm, calculate the fringe width w. Give your answer in millimetres. Answer: mm +
