THE CONCEPTS OF LIGHT Mirrors: Image Formation  LEARNING OBJECTIVES 1. Distinguish between plane and spherical mirrors. 2. Differentiate between real and virtual images. 3. Recognize the significance of light in comprehending mirror concepts. THE MIRROR How does it work? TWO TYPES OF MIRROR  TWO TYPES OF MIRROR 1. PLANE MIRROR 2. SPHERICAL MIRROR Concave Convex What type of mirror you brought in class today? 1. PLANE MIRROR 2. SPHERICAL MIRROR Concave Convex What type of mirror is this? concave mirror: magnifies the reflection when the object is placed within the focal length of the mirror.  1. PLANE MIRROR a mirror with a flat (planar) reflective surface PLANE MIRROR Common mirrors we use everyday It reflects a VIRTUAL image Real Image vs Virtual Image Real image Virtual image Image which Image which appears to be appears to be formed where light formed when light actually converges rays coming from an after a reflection. object do not meet. VIRTUAL IMAGE object Virtual image REAL IMAGE vs VIRTUAL IMAGE REAL IMAGES VIRTUAL IMAGES Produced by diverging Produced by intersecting rays rays Cannot be projected on a Can be projected on a screen screen Formed with the help of a Formed by two opposite diverging lens or a convex lens, concave and convex mirror Always inverted Always upright or erect We CAN reach to it We CAN’T reach to it Plane mirrors reflect virtual image Image is upright x Image appears same distance from the mirror as the object appears to be. Creates a left to right reversal.  2. SPHERICAL MIRROR Mirrors in which curved reflecting surface forms a part of a sphere. TWO TYPES OF SPHERICAL MIRROR  2.a CONCAVE MIRROR Curved inward like a hollow. Can produce virtual or real image. CONCAVE MIRRORS  2.b CONVEX MIRROR Light diverges or spreads out. Can only produce virtual image. CONVEX MIRRORS  SPHERICAL MIRRORS CONCAVE CONVEX CONCAVE vs CONVEX MIRRORS CONCAVE MIRROR vs CONVEX MIRROR “Converging Mirror “Diverging Mirror” (of lines) tend to meet at a point (of lines) tend to move at different direction Why is the word AMBULANCE in front of the vehicle written backward? 1. Plane mirrors reflect real image. TRUE FALSE 2. Concave mirrors have curved inward structures. TRUE FALSE 3. A convex mirror is also known as a diverging mirror. TRUE FALSE 4. The side mirrors and the rear view mirror of cars are made up of convex mirrors. TRUE FALSE 5. The word “AMBULANCE” is written in normal position in front of the ambulance vehicle. TRUE FALSE What’s your Score! Secret Revelation “My Favorite Person” Please do not tell to anybody…  Secret Revelation “My Favorite Person” Please do not tell to anybody… Look in the mirror…  “Mirrors show us what we look like, not who we are”  It’s your turn to share a quote regarding mirrors
