It's a diffraction pattern, not a simple projection. Yes, you need to use the formula.songoku said:
Is formula for horizontal separation the same as vertical distance? What I learned so far is all about vertical distance measured from central maxima.haruspex said:
Looks right.songoku said:
The horizontal separation of fabric can be determined by measuring the distance between the peaks or valleys in the diffraction pattern. This distance is known as the diffraction spacing and is directly related to the spacing between the threads in the fabric.
A diffraction pattern is a pattern of light and dark bands that is produced when light passes through a regular pattern of small openings or obstacles. In the case of fabric, the diffraction pattern is created by the spaces between the threads in the fabric.
Determining the horizontal separation of fabric is important because it can provide information about the quality and characteristics of the fabric. It can also help in identifying the type of fabric and its intended use.
The horizontal separation of fabric in a diffraction pattern can be affected by various factors such as the type of fabric, the thickness of the threads, the spacing between the threads, and the angle at which the light is passing through the fabric.
Yes, the horizontal separation of fabric can also be determined using other methods such as microscopic analysis or physical measurements. However, diffraction patterns are often used because they are non-destructive and can provide quick and accurate results.
