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…

Virtual Images
Introduction A virtual image is a type of image formed when the outgoing rays from a point on an object diverge. The apparent intersection of these diverging rays occurs behind the plane of the mirror or lens, thus giving the illusion that light comes from this intersection point, even though the light is actually diverging.…
