22.A multiple slit diffraction grating has a slit separation of 2.50 ? 10?6 m. Find the wavelength of the monochromatic light that will have its second order bright fringe diffracted through an angle of 38.0°. (1 nm = 10?9 m)
In a single slit diffracion experiment, the width of the slit is3.1x10^-5 m and the distance from the slit to the screen is 2.2 m.If the beam of light of wavelength 600 nm passes through the slitand forms a diffraction pattern on the screen, what is the lineardistance on the screen from the center of the diffraction patternto the first dark fringe?A) 8.5 cmB) 2.1 cmC) 7.4 cmD) 6.3 cmE) 4.3 cm
