    X-ray diffraction is a powerful technique used to determine the atomic and molecular structure of crystalline materials. By analyzing the interference patterns produced by X-rays scattering off the crystal lattice, we can derive valuable information about the arrangement of atoms within the crystal. This chapter will introduce the basics of X-ray diffraction and its applications.…

    5.1 Introduction to Diffraction Diffraction is a phenomenon that occurs when light waves encounter an obstacle or an aperture, causing them to bend and spread out. There are two main types of diffraction: Fresnel diffraction and Fraunhofer diffraction. This chapter will discuss the basic principles and differences between these two types of diffraction. 5.2 Fresnel…

    3.1 Introduction to Interference Interference is a fundamental phenomenon in wave theory that occurs when two or more waves superpose to form a resultant wave. The principle of superposition states that when two or more waves overlap, the displacement at any point is the vector sum of the displacements of the individual waves. In the…

    Introduction Babinet’s Principle, named after French physicist Jacques Babinet, is a theorem concerning diffraction in the field of optics. The principle states that the diffraction pattern from an opaque body is identical to the pattern from a hole of the same size and shape except for the overall forward beam intensity. Statement of Babinet’s Principle…

    Introduction The Airy disk is the bright spot at the center of a pattern that is produced when a plane wave of light is diffracted by a circular aperture. It is named after the British astronomer Sir George Biddell Airy. The pattern consists of a bright central region, or disk, surrounded by a series of…

    Introduction Optics is a branch of physics that studies the behavior and properties of light, including its interactions with matter and the construction of instruments that use or detect it. Optics usually describes the behavior of visible, ultraviolet, and infrared light. Nature of Light Light is an electromagnetic wave, and its speed in a vacuum…

    Introduction Diffraction is a wave phenomenon that occurs when a wave encounters an obstacle or a slit that is comparable in size to its wavelength. It is characterized by the bending and spreading out of waves past the obstacle or through the slit. The Principle of Diffraction Diffraction is a result of the wave nature…

    Introduction X-ray diffraction (XRD) is a powerful technique used for the study of crystalline materials. By analyzing the way in which a beam of X-rays diffracts off a crystalline sample, one can determine the atomic and molecular structure of the material, including bond lengths and angles, atomic positions, and overall symmetry. The Principle of XRD…
