Coherent light with wavelength 601 nm passes through two very narrow slits and the interference pattern is observed on a screen a distance of 3.00 m from the slits. the first-order bright fringe is a distance of 4.84 mm from the center of the central bright fringe. for what wavelength of light will the first-order dark fringe (the first dark fringe next to a central maximum) be observed at this same point on the screen?

Scientific classification

  concave means having an outline or surface that curves inward like the interior of a circle or sphere. so the mirror curves inward.

How is it possible that phylogenies based on sequences from nuclear genomes and organellar genomes (i.e., chloroplasts and mitochondria) from the same group of species yield phylogenetic trees with different branching orders?   answer :   the genome of the endosymbiont is more closely related to members of the group in which it originally evolved, while the nuclear genome of the engulfing organism has its own evolutionary trajectory.
