Before you read this, I suggest you read post 19.20. In post 22.13, we saw that we couldn’t use a microscope to find the positions of atoms in molecules. But, in principle, we should be able to obtain some information from an x-ray diffraction pattern. This post gives more details. X-rays are scattered by the… Continue reading 22.14 X-ray diffraction

Before you read this, I suggest you read post 22.12. In post 22.12, we saw that, in the microscope, the first stage of image formation was formation of a diffraction pattern in a plane that I have labelled the diffraction plane. Waves then continued to form an image, so that the image of point A… Continue reading 22.13 Resolution of the microscope
