A diffraction pattern forms when light passes through a single slit. The wavelength of the light is 525 nm. Determine the angle that locates the first dark fringe when the width of the slit is (a) $1.80 \times 10^{-4}$ m and (b) $1.80 \times 10^{-6}$ m.

Step 1
80x10^-4 m. The formula to calculate the angle for the first dark fringe in a single-slit diffraction pattern is given by: sin(θ) = λ / a where θ is the angle, λ is the wavelength of the light, and a is the width of the slit. Show more…
