http://hyperphysics.phy-astr.gsu.edu/hbase/phyopt/gratint.html WebFeb 27, 2024 · In the single slit (width = 0.1mm), we find the first maximum at an angle of 0.286 degrees. Now lets take a diffraction grating of the same width with 1000000 slits carved into it. The equation: dsin (x)= (lambda). d=10^-10. Now the first maximum does not even appear on the screen.
