  1. QUARTER 2-LESSON 4-5 LIGHT: MIRRORS AND LENSES

  2. At the end of the lesson, you will be able to: predict the qualitative characteristics (orientation, type, and magnification) of images formed by plane and curved mirrors and lenses

  3. At the end of the lesson, you will be able to: Apply ray diagramming techniques in describing the characteristics and positions of images formed by lenses

  4. At the end of the lesson, you will be able to: Identify ways in which the properties of mirrors and lenses determine their use in optical instruments (e.g., cameras and binoculars)

  5. At the end of the lesson, you will be able to: Identify the properties of visible light as it undergoes reflection and refraction and how images can be formed out of these properties.

  6. THUMBS UP OR TRHUMBS DOWN

  7. THUMBS UP OR DOWN 1. Light travels in straight lines unless it is refracted or reflected. TRUE OR FALSE

  8. THUMBS UP OR DOWN 1. Light travels in straight lines unless it is refracted or reflected. TRUE OR FALSE

  9. THUMBS UP OR DOWN 2. Refraction occurs because light changes speed when it passes from one medium to another. TRUE OR FALSE

  10. THUMBS UP OR DOWN 2. Refraction occurs because light changes speed when it passes from one medium to another. TRUE OR FALSE

  11. THUMBS UP OR DOWN 3. When light passes from a denser medium to a rarer medium, it bends away from the normal. TRUE OR FALSE

  12. THUMBS UP OR DOWN 3. When light passes from a denser medium to a rarer medium, it bends away from the normal. TRUE OR FALSE

  13. THUMBS UP OR DOWN 4. Convex mirrors cause light rays to converge at a single point. TRUE OR FALSE

  14. THUMBS UP OR DOWN 4. Convex mirrors cause light rays to converge at a single point. TRUE OR FALSE

  15. THUMBS UP OR DOWN 5. The focal length of a mirror is the distance from the mirror's surface to its focus. TRUE OR FALSE

  16. THUMBS UP OR DOWN 5. The focal length of a mirror is the distance from the mirror's surface to its focus. TRUE OR FALSE

  17. Who am I? • Where can you see me?

  18. How do you see yourself in a mirror?

  19. How do you compare the way you look and how your image look in front of a mirror?

  20. How does your image formed in a mirror?

  21. REFLECTION It is a branch of biology concerned with the study of genes, genetic variation and heredity in organism.

  22. REFLECTION is the bouncing of light rays when it hits a surface just like a mirror.

  23. plane mirrors A process by which genetic information is passed on from parent to child.

  24. Heredity A process by which genetic information is passed on from parent to child.

  25. Regular Reflection The angle of incidence is equal to the angle of reflection.

  26. Regular Reflection All regular reflection is a reflection of smooth surfaces (plane and shiny).

  27. Irregular/Diffused Reflection is a reflection of rough surfaces.

  28. Irregular/Diffused Reflection is a reflection of rough surfaces.

  29. Regular/Irregular Reflection ACTIVITY 1 THE FLOW OF BLOOD

  30. Regular/Irregular Reflection ACTIVITY 1

  31. Regular/Irregular Reflection ACTIVITY 1

  32. Regular/Irregular Reflection ACTIVITY 1

  33. Regular/Irregular Reflection ACTIVITY 1

  34. Laws of Reflection 1.The angle of incident ray is equal to the angle of reflected ray.

  35. Laws of Reflection 1.The angle of incident ray is equal to the angle of reflected ray.

  36. Laws of Reflection 2.The angle between the normal line and the reflected ray is the angle of reflection.

  37. Laws of Reflection

  38. Laws of Reflection Normal Line- imaginary line that can be drawn perpendicular to the surface of the mirror.

  39. Char. that is formed by a plane Mirror 2.The angle between the normal line and the reflected ray is the angle of reflection.

  40. Char. that is formed by a plane Mirror

  41. Char. that is formed by a plane Mirror

  42. Char. that is formed by a plane Mirror

  43. Char. that is formed by a plane Mirror The distance is the same.

  44. Char. that is formed by a plane Mirror

  45. Char. that is formed by a plane Mirror

  46. ACTIVITY 3 ACTIVITY 1 THE BREATHING MECHANISM THE FLOW OF THE AIR TO THE BODY ACTIVITY 4 ACTIVITY 2 ACTIVITY 1 THE HUMAN HEART THE LUNGS ACTIVITY 5 THE FLOW OF BLOOD

  47. USES OF plane Mirror Plane mirrors are used to see ourselves

  48. USES OF plane Mirror Plane mirrors are used as blind turns of some busy roads to see the vehicles coming from the side.

  49. USES OF plane Mirror Plane mirrors are fixed on the inside walls of certain shops e.g. Jewelry shops to make them look bigger

  50. USES OF plane Mirror used in making periscopes which is used in submarines
