Consider a beam of electrons in a vacuum, passing through a very narrow slit of width 2.00μm. the electrons then head toward an array of detectors a distance 0.9090 m away. these detectors indicate a diffraction pattern, with a broad maximum of electron intensity (i. e., the number of electrons received in a certain area over a certain period of time) with minima of electron intensity on either side, spaced 0.521 cm from the center of the pattern. what is the wavelength λ of one of the electrons in this beam? recall that the location of the first intensity minima in a single slit diffraction pattern for light is y=lλ/a, where l is the distance to the screen (detector) and a is the width of the slit. the derivation of this formula was based entirely upon the wave nature of light, so by de broglie's hypothesis it will also apply to the case of electron waves.

Will give brainliest! which statement best describes the similarities between fundamental forces? electromagnetic and strong nuclear forces influence the interaction between charged particles within an atom. gravitational and magnetic forces are both types of charges that occur in nature. nuclear and magnetic forces are both related to mass and weight. strong nuclear force is most like electrical force because they are both related to distance.
