The relationship between the slit width and the diffraction light intensity pattern.

Light has wave-like properties.

I believe it is unnecessary to explain again that light has wave properties and that various optical phenomena change depending on its wavelength. Now, to organize the changes in the wavelength of light and the slit diameter that will be discussed, we will introduce parameters. λ: wavelength of light, D: slit diameter, which, as can be understood from the dimensions of the numerator and denominator, becomes a dimensionless number. As α becomes smaller, the diffraction intensity pattern of Fraunhofer diffraction mentioned earlier takes the shape shown on the right side of the figure, while as α becomes larger, it takes the shape on the left side. Now, considering λ as constant, the shapes produced will change depending on whether D is large or small. Here, I will expand a little on the equations to induce the reader's drowsiness and disguise the thin content. *For more details, please refer to the related links or feel free to contact us.*
