(18) SNC2D – Light and Optics – January 13th to January 17th 2014 (FLIP WEEK) Date Mon Jan 13th Topic/Activities Lens Basics 1. Converging Lens 2. Diverging Lens 3. Terminology of Converging Lenses 4. Terminology of Diverging Lenses Homework Learning Goals I will be able to distinguish between shape of converging (convex) and diverging (concave) lenses I will be able to communicate the properties of converging and diverging lenses Using ray diagrams, I will be able to determine how light achieves a principal focus point after passing through a lens Success Criteria key terminology: converging lens, convex lens, diverging lens, concave lens, axis of symmetry, optical centre, principal focus, secondary principal focus, principal axis, incident ray, refracted ray, focal length label convex and concave lenses a converging lens brings parallel light rays together through a focus after refraction a diverging lens spreads parallel light rays apart after refraction so that it looks as if they have come from a virtual focus the principal focus of a converging lens in on the OPPOSITE side of the lens as the incident rays the principal focus of a diverging lens is on the SAME side of the lens as the incident rays Diverging Lenses (a.k.a. Concave Lenses) 1. Concave lens ray characteristics (diverging) 2. Images formed by a concave lens 3. How to locate the image in a concave lens Copy table 11.6 on page 451 into your notes. I will be able to explain the three rules for diverging lens imaging I will be able to predict image characteristics for a light source at various distances from diverging lens Using a ray diagram, I will be able to locate virtual image formed by diverging lens I will be able to explain the three rules for converging lens imaging I will be able to predict image characteristics for a light source at various distances from converging lens Using a ray diagram, I will be able to locate virtual image formed by converging lens Learning Checkpoint p. 454 # 1, 2 Complete concave ray diagram practice sheet Complete Mirror/Lens review sheet for your notes Tues Jan 14th QUIZ: Mirrors (terminology, ray diagrams for plane, concave, and convex mirrors, calculating magnification, applying SALT, NEED A SCIENTIFIC CALCULATOR!) Converging Lenses (a.k.a. Convex Lenses) 1. Convex lens ray characteristics (converging) 2. Images formed by a convex lens 3. How to locate the image in a convex lens Learning Checkpoint p. 454 # 3, 4, 5 Complete convex ray diagram practice sheet key terminology: diverging lens (concave) a diverging lens always produces a smaller, upright, virtual image, on same side as object label a diverging lens ray diagram with optical centre, F, 2F, F’, 2F’, principal axis, axis of symmetry key terminology: converging lens (convex) when an object is beyond 2F’ the image is smaller, inverted, located between 2F and F, and is real when an object is at 2F’, the image is the same size, inverted, located at 2F, and is real when an object is between 2F’ and F’, the image is larger, inverted, beyond 2F, and is real when an object is at F’, no clear image is formed when inside of F’, the image is larger, upright, on the same side at the object (behind lens), and is virtual Date Wed Jan 15th Topic/Activities QUIZ: Index of Refraction and Snell’s Law (calculate index of refraction and/or speed of light in a medium, use Snell’s Law, be able to draw and label refracted ray diagram, NEED A SCIENTIFIC CALCULATOR!) Human Perception of Light & The Human Eye 1. How do we perceive light? 2. Anatomy of the human eye 3. Human vision and light detection 4. Correcting vision problems using lenses Homework Complete guided note on Human Perception of Light Learning Checkpoint p. 473 # 1, 2, 3, 4, 5 p. 481 # 2, 3, 5, 6, 7 Complete guided note on Correcting Vision Problems Using Lenses Read pages 476 to 477 and answer Learn Checkpoint p. 475 # 1, 2, 3, 4 p.477 # 1, 2, 3, 4. Thurs Jan 16th Learning Goals I will be able describe the eye and explain how accommodation controls sight in the eye I will be able to understand vision problems such as myopia, hyperopia, and presbyopia I will be able to describe how lenses, such as a positive meniscus, a negative meniscus, or contact lenses, improve human eyesight Success Criteria Light and Optics REVIEW Period Unit Test Monday January 20th Unit Test REVIEW QUESTIONS Physics Unit Summary – pp. 500 - 501 This section outlines key unit concepts and vocabulary.
