1 Physics S4 Graphical construction of images Lesson 159 Developed by (Tomas Odenyo Oloo) 50 minutes Class discussion Subtopic Graphical construction of images Overview Graphical construction of images Overview During this lesson, the teacher shall explain to the learners how to find images In curved mirrors by graphical method. Two rays of light are needed to locate an image of an object as seen in a curved mirror. The two rays from a point on Specific Objectives Find images formed by graphical methods the object converge or appear to diverge from a point. Curved mirrors are used as driving mirrors and by dentists because they can give magnified images.. Lesson Objectives Find images formed by graphical methods Linked to other lessons This lesson is linked to the lesson on curved mirrors Evaluation At the end of this lesson, learners shall be able to: Find images formed by graphical methods

2 Step1 Introduction Duration: 5 minutes The teacher introduces the lesson by illustrating to the learners the behavior of two rays falling on a curved mirror before and after reflection as in the diagrams below. One ray, originally parallel to the principle axis is reflected through the focal point of the mirror and the other one which passes through the focal point is reflected parallel to the principle axis. How to achieve this learning This is a class discussion in which the learners ask and answer questions Step 2 How to conduct the lesson Activity Graphical construction of images Duration: 45 minutes Class organization : Class discussion

3 Instruction to the learners: Ask the learners to write down the laws of reflection in plane mirrors The following is the expected outcome Images formed by concave mirror To construct the image of an object, two rays are necessary. The two rays converge at a point after reflection and the position of the image is located. 1) Consider a small object placed at a distance beyond twice the focal length of the mirror as below Two rays of light from point 0 of the object converge at point I hence forming the image The image formed is upside down, smaller than the object and it is a real image The image is formed between the focal point and a distance twice the focal point. 2) Consider a small object placed at a distance twice the focal length of the mirror as below Two rays of light from point 0 of the object converge at point I hence forming the image. The image formed is upside down, same size as the object and it is a real image Image formed by a convex mirror To construct the image of an object, two rays are necessary.

4 The two rays converge at a point after reflection and the position of the image is located. Consider a small object placed at a distance a convex mirror as below Rays of light appear to diverge from points behind the mirror as shown. The image formed is upright, virtual and smaller than the object Convex mirrors form images which are virtual, i.e. not real because the rays just appear to come from a source behind the mirror. Exercise A small object is placed on the principle axis of a concave mirror of focal length 10cm at a distance of 15cm from the mirror. By graphical method find the position of the image formed and the nature of the image formed. Answer

5 -The image is 30cm from the mirror - It is upside down, real and larger than the object Method of evaluation: Evaluate the learners basing on the correct image drawn and nature stated Conclusion In summary of this lesson make sure that the learners are able to: Find images formed by graphical methods Homework Duration: open Resources needed textbooks Class organization: individual work Instruction to the learners: Solve the problem below Question A small object is placed on the principle axis of a convex mirror of focal length 8cm at a distance of 12cm from the mirror. By graphical method find the position of the image formed and the nature of the image formed.

6 Answer The image is 4.8cm behind the mirror, it is virtual, upright and smaller than the object Evaluation criteria: correct image drawn and nature stated Reference: Tom, Duncan (2000) Advanced Physics, 4 th Edition, Great Britain (p 82 )
