A double-slit experiment is set up using red light (λ = 711 nm). A first order bright fringe is seen at a given location on a screen.

1)What wavelength of visible light (between 380 nm and 750 nm) would produce a dark fringe at the identical location on the screen?

λ =

2) A new experiment is created with the screen at a distance of 1.9 m from the slits (with spacing 0.11 mm). What is the distance between the second order bright fringe of light with λ = 698 nm and the third order bright fringe of light with λ = 409 nm? (Give the absolute value of the smallest possible distance between these two fringes: the distance between bright fringes on the same side of the central bright fringe.)

Consider the following experiment: a double-slit set-up for firing electrons one at a time. Let's now add a second electron (orange), which is fired parallel to the first one, but in the opposite direction, and so as to pass closer to one slit than the other, and, importantly, above the plane in which interference occurs: The firing of the two electrons is timed so that the orange electron is "closest" to the purple electron somewhere around point P, i.e. after...
