Example \(\PageIndex{1}\): Calculating Single-Slit Diffraction Visible light of wavelength 550 nm falls on a single slit and produces its second diffraction minimum at an angle of 45.0° relative to the incident direction of the light, as in Figure \(\PageIndex{5}\).
Single Slit Diffraction Formula. As explained in the Interference of Waves, the path difference between the two waves after passing through the slit must be a whole multiple of wavelength in order to observe a constructive interference (bright region) or a half multiple of wavelength for destructive interference (dark region). The equations for ...
We can use Equation 3.4.3 for finding the angular deviation from the center line for a single slit, but it requires the wavelength of the wave as well as the slit gap. We have the latter, but we need to calculate the former.
Calculate the features of diffraction gratings: diffraction grating calculator. Compute diffraction properties, such as Rayleigh angle and diffraction pattern. Single-slit, double-slit, multiple-slit, diffraction grating, circular apertures.
A slit width equal to the wavelength of the laser light would spread the first minimum out to 90° so that no minima would be observed. The relationships between slit width and the minima and maxima of diffraction can be explored in the single slit calculation.
