Question

1) A double-slit experiment is set up using red light (A = 703 nm). A first order bright fringe is seen at a given location on a screen. What wavelength of visible light (between 380 nm and 750 nm) would produce a dark fringe at the identical location on the screen? A = nm Submit You currently have 0 submissions for this question.

What is the distance between the second order bright fringe of light with = 691 nm and the third order bright fringe of light with A = 404 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.) 1x1 = m Submit You currently have 0 submissions for this question.
