Working Example: Light with a wavelength of 511 nm forms a diffraction pattern after passing through a single slit of width 2.20x10^-6 m. Find the angle associated with (a) the first and (b) the second dark fringe above the central bright fringe.
Added by Andrew C.
Step 1
Given: Wavelength (λ) = 511 nm = 511 x 10^-9 m Width of the slit (a) = 2.20 x 10^-6 m Using the formula for a single slit diffraction pattern: sin(θ) = Nλ / a Substitute the values: sin(θ) = (1 x 511 x 10^-9) / (2.20 x 10^-6) Calculate the angle: sin(θ) = Show more…

A diffraction pattern forms when light passes through a single slit. The wavelength of the light is 586 nm. Determine the angle that locates the first dark fringe when the width of the slit is (a) 1.8 × 10-4 m and (b) 1.8 × 10-6 m.

Calculate Light with a wavelength of $676 \mathrm{~nm}$ passes through a slit $7.64 \mu \mathrm{m}$ wide. What is the angle to the first dark fringe above the central bright fringe?
Light of wavelength 440 $\mathrm{nm}$ passes through a double slit, yielding a diffraction pattern whose graph of intensity $I$ versus angular position $\theta$ is shown in Fig. $36-44$ . Calculate (a) the slit width and (b) the slit separation. (c) Verify the displayed intensitities of the $m=1$ and $m=2$ interference fringes.
