A double slit experiment produces an interference pattern on a screen 2.8 m away from the slits. Light of wavelength = 480 nm falls on the slits from a distant source. The distance between adjacent bright fringes is 5.8 mm.

a) find the distance between the two slits. Express your answer using 3 significant figures.

b) determine the distance to the 6th order dark fringe from the central fringe. Express your answer using three significant figures.

A physics instructor wants to produce a double-slit interference pattern large enough for her class to see. For the size of the room, she decides that the distance between successive bright fringes on the screen should be at least 2.80 cm. If the slits have a separation d=0.0200mm, what is the minimum distance from the slits to the screen when 632.8-nm light from a He-Ne laser is used? Express your answer to three significant figures.

Two narrow slits are used to produce a double-slit interference pattern with monochromatic light. The slits are separated by 8 mm, and the interference pattern is projected onto a screen 7 m away from the slits. The central bright fringe is at a certain spot on the screen. Using a ruler with one end placed at the central fringe, you move along the ruler passing by two more bright fringes and find that the next bright fringe is 23.5 mm...

In a double-slit experiment, the distance between slits is 0.5.0 mm and the slits are 2.0 m from the screen. Two interference patterns can be seen on the screen: one due to light of wavelength 480 nm, and the other due to light of wavelength 600 nm. What is the separation on the screen between the second -order (m = 3) bright fringes of the two interference patterns?(show the ray diagrams)

Problem about double-slit interference. a) Choose and state a wavelength in the electromagnetic spectrum that corresponds to visible light. b)We would like it to be easy to measure the positions of the dark and bright fringes so let’s aim for having a distance of 1cm between adjacent bright fringes. Choose the distance of the screen and the distance between the slits so that this is the case. The slit distance should be much bigger than the wavelength, but much smaller...
