    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…

    Introduction Huygens’ Principle, named after the Dutch physicist Christiaan Huygens, is a fundamental concept in wave theory. It provides a comprehensive way to predict and understand how waves propagate in different media. Basic Concept Huygens’ Principle states that every point on a wavefront is itself the source of spherical wavelets, and the new wavefront is…
