The Figure Shows the Resulting Pattern When a Single Slit $0.3 \times 10 ^ { - 3 } \mathrm {~m}$

Short Answer

The figure shows the resulting pattern when a single slit is illuminated by monochromatic light. The slit is $0.3 \times 10 ^ { - 3 } \mathrm {~m}$ wide and is illuminated by light of wavelength $506 \mathrm {~nm}$ . A diffraction pattern is seen on a screen $2.8 \mathrm {~m}$ from the slit. What is the linear distance on the screen between the first two diffraction minima on either side of the central diffraction maximum?
