A beam of electrons hits a pair of slits spaced a distance d apart (center-to-center). The wavelength of the electrons is 23.8 nm. After traveling through the slits, the electrons form an interference pattern on a screen located a distance 0.750 m from the slits. If the center of the second 'bright' fringe occurs 2.30 cm from the center of the central bright fringe on the screen, what is the separation, d, between the slits? How fast are the electrons...

Two thin parallel slits that are 0.0117 mm apart are illuminated by a laser beam of wavelength 620 nm. (a) On a very large distant screen, what is the total number of bright fringes (those indicating complete constructive interference), including the central fringe and those on both sides of it?

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...

Monochromatic light of wavelength λ1 is sent through two closely-spaced slits separated by a distance d1 = 1.8 mm. A resulting interference pattern is shown on a screen L1 away. Another monochromatic light source, this one of wavelength λ2, is sent through a diffraction grating toward the same screen, resulting in a second interference pattern. The diffraction grating is a distance L2 from the screen and has 400 lines per mm etched onto it. A) Assume that L1 = L2...
