  1. 1. The Optics FilesThe Optics FilesUsing Mirrors and Lenses
  2. 2. Key Objectives:Key Objectives:The student will investigate andunderstand the interaction oflight waves
  3. 3. Key Objectives:Key Objectives:Predict the characteristics ofthe images formed by lensesand mirrors– Illustrate and describe reflectionand refraction of visible light
  4. 4. Key Objectives:Key Objectives:Describe the behavior of lightwaves– Understand that light travels instraight lines and is reflected,absorbed or transmitted
  5. 5. Key Objectives:Key Objectives:– Understand that light travelsthrough media and undergoes achange in speed that causes it tobend when it does so
  6. 6. Key Objectives:Key Objectives:– Understand that when lightstrikes an uneven surface orpasses through an opening it canreflect or diffract
  7. 7. Key Objectives:Key Objectives:– Understand constructive anddestructive interferenceregarding light waves
  8. 8. Law of ReflectionStates that the angle of incidence(direction in) is equal to the angleof reflection (direction out)
  9. 9. ReflectionThe bouncing back of a ray oflight, sound or heat when it hitsa surface
  10. 10. Plane MirrorA mirror with a flat smoothsurface it reflects a ‘true’reversed image– Bathroom Mirror
  11. 11. Concave MirrorA mirror that is curved inward.(Like a bowl) It reflects an uprightlarger image when inside thefocal point and an invertedsmaller image when outside thefocal point– Compact or Make-up mirror
  12. 12. Convex MirrorA mirror that bends outward fromthe center. It reflects a distortedsmaller image but allows you tosee around corners.– Bus mirrors– Security mirrors
  13. 13. DiffractionThe change in direction of wavesas they bend around acorner/edge or around anobstacle or pass through anopening or slit.
  14. 14. RefractionThe bending of light as light wavespass through different mediums
  15. 15. Concave LensA lens that bends inward to center.The light waves move outward as theypass through causing an image on theother side to appear smaller.– Glasses
  16. 16. Convex LensA lens that bends outward from thecenter.
  17. 17. Convex LensAs light passes through, it focusesthe light into a fine beam and thelight and images on the other sideappear larger– Magnifying glasses– Reading glasses
  18. 18. InterferenceThe combination of two or morewaves that results in a single wave.
  19. 19. Essential LearningsLight waves travel in straight linesuntil they strike an object and thenthey are either reflected, absorbedor transmitted
  20. 20. Essential LearningsReflection is the “bouncing back” oflight waves– There is a Law that governsreflection stating that the Angle ofIncidence = Angle of Reflection
  21. 21. Essential LearningsRefraction is the slowing andbending of light waves as lightpasses through a medium
  22. 22. Essential LearningsThere are three types of mirrorsthat reflect light– Plane– Concave– Convex
  23. 23. Essential LearningsPlane Mirror - Reflects a truesized image, upright and reversed
  24. 24. Essential LearningsConcave Mirror –Makesa larger upright imageinside the focal point, asmaller inverted imageoutside the focal point
