2 6Px 27 Pipiri 2014 What we will do What we will learn Preliminaries and roll The importance of starting well Read an important notice That some things, but not many, are more important than Physics. Revisit the Y9 practicals for curved mirrors and extend the ideas, with notes, to Y12 work What concave and convex mirrors are. Terms: focus, virtual focus, pole, principal axis, radius of curvature, magnification – 2 ways Make notes on the 3 key rays for curved mirrors. AND how to find the image and its nature. Firstly concave then convex. What the 3 key rays are. What sort of image is formed and how to describe it. Examples plus new HW given. Set a due date for the HW. How to tackle curved mirror questions using ray diagrams

3 Today is Alicia’s birthday Important Notice

4 HW item Skills practiced Waves: unit 1 Due Fri the 13 th of June Wave Properties, definitions and relationships Waves: units 2 and 3 Due Tues the 17 th of June Reflection and transmission PLUS Behaviours of Water Waves Waves: unit 4 Due Thurs the 19 th of June Diffraction of waves Waves: unit 5 Due Monday the 23 rd of June Superposition and Interference (Twin Source Interference) Waves: unit 6 Due Monday the 23 rd of June Reflection of light from plane mirrors Waves: unit 7 Due Zenday the 93 rd of Octember Reflection of light from curved mirrors. Ray diagrams only

5 No. of marks What for 1 Having sketches and FULL working 1 Neat presentation and down-page format 1 Answer underlined and units given 1 Self marked and all correct – eventually 1 In on time and signed for (“This is my own work”…….) Total A mark out of five that will contribute to the “homework” grade in the reports

11 Concave mirror with the object between the mirror and the focus – 3 rays to find the image

12 Concave mirror with the object between the focus and the centre of curvature – 3 rays to find the image

13

14 Concave mirror with the object between outside the centre of curvature – 3 rays to find the image

15 Special case: Concave mirror with the object on the focus – 3 rays to find the image (or the lack of it)
