P5h Ray Diagram Sheets

  1. 1. Drawing Ray Diagrams <ul><li>Method </li></ul><ul><li>Draw a horizontal line (axis) and mark out the positions of the lens and the focal point on it. </li></ul><ul><li>The question will probably tell you the focal length of the lens and the focal point will be this distance away from the centre of the lens. </li></ul><ul><li>Draw the object the correct distance away from the lens. Make sure it is the correct height. </li></ul><ul><li>Draw a line from the top of the object, straight through the centre of the lens and out the other side. </li></ul><ul><li>Light through the centre of the lens is not refracted. </li></ul><ul><li>Draw a line parallel to the axis until it meets the lens. Now draw a line from that point, through the focal point. </li></ul><ul><li>Light parallel to the axis is refracted through the focal point. </li></ul><ul><li>5. Where your two lines cross is the top of the image. Draw it in! </li></ul>1. Draw a ray diagram for showing the image formed when with a lens of focal length f = 3 cm when a 2 cm high object is 8 cm from the lens. 2. Draw a ray diagram for showing the image formed when with a lens of focal length f = 3 cm when a 2 cm high object is 6 cm from the lens.
  2. 2. 4. Draw a ray diagram for showing the image formed when with a lens of focal length f = 3 cm when a 2 cm high object is 2 cm from the lens. 3. Draw a ray diagram for showing the image formed when with a lens of focal length f = 3 cm when a 2 cm high object is 5 cm from the lens.
