PhysicsMedical PhysicsGCSEAQA Created by: Atlanta and JacobCreated on: 14-09-16 17:36 What can be drawn to find the position and nature of an image formed by a lens? A ray diagram. 1 of 13 What image is formed when an object is placed between a converging lens and F? The image formed is virtual, upright, magnified and on the same side of the lens as the object. 2 of 13 What lens does a camera contain and what is it used to form? A converging lens that is used to form a real image of an object. 3 of 13 What type of lens is a magnifying glass and what is it used to form? A converging lens that is used to form a virtual image of an object. 4 of 13 What can we draw ray diagrams to find? The image that different lenses produce with objects in different positions. 5 of 13 What is the line through the centre of the lens and at right angles to it called? The principal axis, and this should be included in your diagrams. 6 of 13 Why do ray diagra s use three construction rays from a single point on the object? To locate the corresponding point on the image. 7 of 13 What happens to a ray parallel to the principal axis? It is refracted through the principal focus. 8 of 13 What happens to a ray through the centre of the lens? It travels straight on, without refraction. 9 of 13 What happens to a ray through the principal focus? It is refracted parallel to the principal axis. 10 of 13 What are construction rays? Rays drawn on a diagram to determine the position and nature of an image. 11 of 13 Is the image formed in a camera real or virtual? Real. 12 of 13 **LOOK UP AND PRACTISE DRAWING RAY DIAGRAMS TO MAKE SURE THAT YOU HAVE THE CORRET POSITION** ** 13 of 13
