This physics video tutorial provides a basic introduction into the thin lens equation. It explains how to use this equation to calculate the image distance given the focal length of the lens and the object distance. The focal length is positive for a converging lens and negative for a diverging lens. A diverging lens always produces a virtual image. A converging lens can produce a real image or a virtual image. This video on optics contains plenty of examples and practice problems. This tutorial explains how to tell if the image is upright or inverted, enlarged or reduced in size. It explains how to calculate the magnification and image height. This video also explains how to calculate the power of the lens in diopters. • Law of Reflection - Geometric Optics: • • Law of Reflection - Geometric Optics ... • The Mirror Equation: • • Spherical Mirrors The Mirror Equati... • Refraction of Light: • • Refraction of Light • Snell's Law Index of Refraction: • • Snell's Law Index of Refraction Pra... • Total Internal Reflection Critical Angle: • • Total Internal Reflection The Criti... • Thin Lens Equation: • • Thin Lens Equation, Optics, Convergin... • _____________________________ • Ray Diagrams: • • Ray Diagrams • The Huygens Principle: • • Huygens Principle - Physics • Young's Double Slit Experiment: • • Young's Double Slit Experiment • Single Slit Diffraction: • • Single Slit Diffraction - Physics Pro... • Diffraction Grating Problems: • • Diffraction Grating Problems - Physics • Polarization of Light Problems: • • Polarization of light Problems, Malus... • _________________________________ • Final Exams and Video Playlists: • https://www.video-tutor.net/ • Full-Length Videos and Worksheets: • / collections
