if the width of one slit is increased relative to the other the slit separation must decrease and since slit sep is inversely proportional to fringeseparationthe fringes become closer together.
Increasing the slit width in single slit diffraction results in a narrower central maximum and reduced overall diffraction pattern intensity. This is due to increased diffraction spreading caused by wider slit openings.
The width of the slit in single-slit diffraction affects the appearance of the dark fringes by making them narrower and more defined as the slit width decreases.
The width of the slit should be on the order of the wavelength of the light being used for diffraction in order to observe the diffraction pattern clearly. This is known as the single-slit diffraction condition. The size of the slit also affects the angular spread of the diffraction pattern.
The single slit diffraction formula is a special case of the double slit diffraction formula. The double slit formula accounts for interference between two slits, while the single slit formula considers diffraction from a single slit. The double slit formula can be derived from the single slit formula by considering the additional interference effects from the second slit.
In a double-slit experiment, the interference patterns produced by a single slit and a double slit differ in their complexity and visibility. The interference pattern from a single slit is a simple pattern of alternating light and dark bands, while the interference pattern from a double slit is a more intricate pattern of multiple bright and dark fringes.

Wavelength width of the slit
In a double-slit experiment, the interference patterns produced by a single slit and a double slit differ in their complexity and visibility. The interference pattern from a single slit is a simple pattern of alternating light and dark bands, while the interference pattern from a double slit is a more intricate pattern of multiple bright and dark fringes.
Using a slit width comparable to the wavelength in interference experiments helps to maximize the diffraction effects, leading to better-defined interference patterns. This ensures that the interference fringes are well-resolved and allows for accurate measurements of parameters like wavelength or slit separation. Additionally, using a narrower slit width can enhance the contrast and visibility of the interference pattern.
If one slit is closed in a Young's double-slit experiment, the interference pattern will disappear, and you will only observe the pattern corresponding to a single slit. This occurs because interference requires two sources of coherent waves to create the pattern. By blocking one of the slits, you effectively eliminate the second wavefront needed for interference.
When the slit width is less than the wavelength of light, there are not enough disturbances to cause diffraction. Diffraction occurs when light waves encounter an obstacle or aperture that is comparable in size to their wavelength. If the slit width is much smaller than the wavelength, the wavefronts are not significantly disturbed, and diffraction effects are minimized.
Only one ruling will be there along with a slit in a grating element. The combined width of a ruling and a slit is called grating element.
The interference pattern produced by a single slit consists of a central bright fringe with alternating dark and bright fringes on either side. In contrast, the interference pattern produced by a double slit consists of multiple bright fringes with dark regions in between, known as interference fringes. The double slit pattern is more complex and exhibits a higher degree of interference compared to the single slit pattern.
