How Does a Lens Form an Image? | Image Formation by a Lens Explained Simply Have you ever wondered how a lens forms an image? In this video, we take a fun and visual journey into the world of optics to understand image formation by a lens, and why lenses are the key to producing both sharp image quality and high brightness. We begin with a simple example: how light scatters from an object like a statue in sunlight. We explore how rays from different points mix and why placing a sheet of paper in front of the object doesn’t create a visible image. Then, we dive into concepts like spot size, pinhole imaging, and the classic camera obscura effect. Using simulations and ray diagrams, you'll learn: • Why smaller pinholes create clearer images but reduce brightness • What spot size means in optics and how it affects image sharpness • How image quality and brightness are in a constant trade-off • Why a lens is the perfect tool to solve both problems at once This video is perfect for anyone curious about: • How lenses form real images • What happens at the focal point of a converging lens • The difference between pinhole cameras and lens-based systems • How to trace rays and understand their behavior on the CCD sensor • Key optical terms like convex lens, concave lens, refraction of light, and image formation physics 🔍 Whether you're a student, hobbyist, or just someone interested in the physics of lenses, this video breaks down everything you need to know about how a lens forms an image in a simple and engaging way. 📌 Topics Covered: • How a lens forms an image • Image formation by a lens and by a pinhole • Image formed in lens and on a CCD • Spot size and image quality • Refraction of light through convex and concave lenses • Camera obscura and imaging history • Real vs. virtual images • Ray tracing basics with light sources • Object at the focal point of a converging lens • The optical trade-off: brightness vs. sharpness Full Course on Udemy: https://www.udemy.com/course/zemax-op... #lensimaging #optics #physics #spotSize #pinholecamera #convexlens #concavelens #realimage #refraction #CCD #raytracing
