A horizontal beam of laser light of wavelength 501 nm passes through a narrow slit that has width 6.20×10−2 mm . The intensity of the light is measured on a vertical screen that is 3.00 m from the slit. Use the result of part A to estimate the width of the central diffraction maximum that is observed on the screen. Express your answer to two significant figures and include the appropriate units.

UN 6 of 17 Constants Part Consider a beam of electrons in a vacuum, passing through a very narrow slit of width 2.00 pm. The electrons then head toward an array of detectors a distance 1.076 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 0.524 cm from the...
