3. 3 What is LIGHT ?

4. 4 Directions: Fill in the blanks in the sentence below. Below each paragraph are words corresponding on the properties and behavior of light that you will encounter in this module. Light is a natural agent that stimulates sight and make things possible. It is a type of energy known as 1. ___________. It is given out by luminous objects such as the sun, light bulbs and laser. It is made up of little packets of energy called 2.___________. Light travels as waves. But unlike sound waves, it does not need any material to carry its energy along. This means that light can travel through a 3. _ ___________ - a completely airless space. Light waves travel out from their source in a straight lines called 4. __________.

5. 5 Light behaves in a variety of ways when it comes in contact with water, air, and other matters. When light strikes matter, a part of light is 6. “__________” into the matter and is transformed into heat energy. If the matter that the light strikes is a transparent material, the light component that was not absorbed within the material is 7. “__________” through and exits to the outer side of the material. If the surface of the material is smooth (a mirror for example), 8.“_________” occurs, but if the surface is irregular having pits and protrusions, the light 9. “__________”.

6. LIGHT a form of energy that is known as an electromagnetic radiation. travels in waves, known as electromagnetic waves. 6

7. 7 LIGHT a form of energy that is known as an electromagnetic radiation. travels in waves, known as electromagnetic waves. Speed of light - 3.0 x 10 8  meters per second through a vacuum. Light can be: REFLECTED ABSORBED REFRACTED

17. 17 Image Characteristics of a PLANE MIRROR Virtual vs. Real Images In the case of plane mirrors, the image is said to be a  virtual . Virtual images are images that are formed in locations where light does not actually reach. Light does not actually pass through the location on the other side of the mirror; it only appears to an observer as though the light is coming from this location. Whenever a mirror (whether a plane mirror or otherwise) creates an image that is virtual, it will be located behind the mirror where light does not really come from. Object Distance is equal to the Image Distance Size of Image is equal to the size of the Object Orientation is always upright

19. 19 Left-Right Image Reversal W hy is the reversal observed in the left to right direction and not in the head to toe direction?  If you look up at a person's shirt from the front, the letters do not appear reversed. But if you could view the lettering on the shirt from "behind the shirt", then the letters would appear reversed. The change in the frame of reference causes the appearance of reversed lettering.

24. 24 The simpler method relies on two rules of reflection for concave mirrors. They are: Any incident ray traveling parallel to  the principal axis  on the way to the mirror will pass through the  focal point  upon reflection. 2. Any incident ray passing through the  focal point  on the way to the mirror will travel parallel to  the principal axis  upon reflection. 1 2

25. 25 Step-by-Step Method for Drawing Ray Diagrams IMAGE CHARACTERSTICS: L ocation = Between C & F O rientation = Inverted S ize = Reduced T ype = Real

26. 26 IMAGE CHARACTERSTICS: L ocation = At C O rientation = Inverted S ize = the same size as the object T ype = Real

27. 27 IMAGE CHARACTERSTICS: L ocation = beyond the center of curvature O rientation = Inverted S ize = Enlarged T ype = Real

28. 28 IMAGE CHARACTERSTICS: L ocation = Behind the mirror O rientation = Upright S ize = Enlarged T ype = Real

29. 29 No Image is formed
