A slit 0.100 cm wide is illuminated by light of wavelength 529. nm creating a diffraction pattern on a screen 284. cm away. How many millimeters are between the first 4 diffraction minima on the same side of the central diffraction maximum?
The distance of the order diffraction from the central maxima is given by the expression
The distance between the first four diffraction minima on the same side of the central diffraction maxima is
Therefore, there is 4.51 millimeters are between the first 4 diffraction minima on the same side of the central diffraction maximum.
