Chapter 6: Multiple-Slit Diffraction
6.1 Introduction Multiple-slit diffraction occurs when light passes through an array of narrow, equally spaced slits, creating an interference pattern of bright and dark regions. In this chapter, we will discuss the basics of multiple-slit diffraction and explore the underlying principles that govern the formation of the resulting patterns. 6.2 Double-Slit Diffraction Double-slit diffraction is…

Chapter 5: Fresnel and Fraunhofer Diffraction
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…

Chapter 4: The Michelson Interferometer
4.1 Introduction to the Michelson Interferometer The Michelson Interferometer is an optical instrument that utilizes interference to measure distances and wavelengths with high precision. It was invented by Albert A. Michelson in the late 19th century and has been used in various scientific experiments, including the famous Michelson-Morley experiment, which tested the existence of the…

Chapter 3: Interference
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…

Chapter 2: Magnification
2.1 Introduction to Magnification In optics, magnification is the factor by which an object’s size appears larger or smaller than its actual size when viewed through an optical instrument, such as a lens or mirror. Magnification can be expressed as a dimensionless value or as a ratio of the size of the image to the…

Chapter 1: Geometric Optics
1.1 Introduction Geometric optics is a field of physics that deals with the study of light and its interaction with various media using the principles of geometry. It is based on the assumption that light travels in straight lines called rays, and it simplifies the analysis of complex optical systems by neglecting the wave properties…
