Geometric. Optics. Presented by: Sestacova Adriana Talmazan Ana Taran Ecaterina Short Overview • General aspects of the Geometric Optics • Convex Spherical Lenses • Concave Spherical Lenses • Ophtalmic Prisms The Lensmaker’s Equation (LME) • The location of the image depends on the location of the object. • The radius of the Geometric optics— The term applied to optical analysis, which considers the propagation of light along ray paths in ordinary 3-dimensional space. It is also called ray optics.

Mirrors, like lenses, can also form images that in turn are captured by your eye. CHAPTER 25 | GEOMETRIC OPTICS … This video has it all.

Up Next. Geometric Optics . Rays and Wave fronts. Real images can be produced by concave mirrors and converging lenses. When we look into a convex mirror or see through a concave lens, what we see is not a real image. This image, which appears to be on other side of the lens or mirror plane, Geometric Optics Purpose: Students will learn about refraction, lenses, and mirrors. Introduction: Few things are as basic as vision.

Students will also be
