Understanding Reflection: Mirrors, Images, and Light Behavior

Reflection is a fascinating phenomenon involving mirrors and light. When we look in a plane mirror, we see an image, not the object itself; light reflects off the surface, changing direction. Convex mirrors produce smaller, upright images, while concave mirrors can enlarge nearby objects and create "real" images. Understanding these principles allows us to appreciate how mirrors affect our daily lives, from personal grooming to optical devices. Dive deeper into the world of reflection and discover how it shapes our perception.

  1. All About Reflection http://www.alaska-in-pictures.com/glacier-lake-reflection-5438-pictures.htm

  2. Misconception We look into mirrors Reality Nothing is happening behind the reflecting surface. Light does not originate from behind the surface of the mirror—it hits the reflecting surface and bounces back.

  3. Plane Mirrors When we look in a plane mirror, we see an image of the object, not the object itself. When a light wave hits a plane mirror, it changes direction and returns to its original medium. Think about it: Imagine you are standing directly in front of a mirror. What happens to the image if you take 10 steps backwards? http://www.smkbud4.edu.my/Data/sites/vschool/phy/wave/reflection.htm

  4. Convex Mirrors Reflect light from all parts of a room to a person’s eye. Images are always upright and smaller than the object, no matter where the object is located. Your eye here http://www.optics4kids.com/teachersparents/articles/lensesgeometricaloptics.html

  5. Concave Mirrors Produce an enlarged image of a nearby object. This type of mirror focuses parallel light rays (brings them to a converging point) Only concave mirrors can produce “real” images http://www.optics4kids.com/teachersparents/articles/lensesgeometricaloptics.html

  6. Why is the image upside down? http://listen.grooveshark.com/#/playlist/COuntry+blueS/39692826

  7. So... What? You have learned about concave/convex mirrors/lenses. Can you think of one type of lens/mirror that we use every single day? Hint: You’re using it to read this slide.
