3. What does light have to do with a bouncing ball?
Any basketball players? If you want to throw a bounce pass to a teammate. Is there anything you notice about the angle of the ball when it hits the floor and then comes back up? It looks like it is the same. Now, what if I changed the surface of the floor? This pass only works if the floor is smooth, right? What would happen if the floor were covered in rocks? Now, imagine if you had many balls hitting a rough, rock surface – what would happen? They would bounce all over the place, right? The reflection of light is similar.

4. Law of Reflection

5. Law of Reflection
The Law of Reflection states that the light ray bounces off the object at the same angle it hits the object.
In more scientific terms, the angle of incidence is equal to the angle of reflection.

8. DO NOW Look yourself in the various objects.
Which objects form images ?
Which objects do not form images ?
What are some similarities between the objects you chose for question #2 ?
Why do you think this happens ?
Yesterday, you began talking about light and its properties. Today, we are going to talk some more about light. I’ll give you a few minutes now to complete the do now.
In the mirror, you see a clear image of yourself. In the foil, if you see anything, you might see a very blurry image. You see things differently because of the different ways they reflect light. Today, we are going to talk more about light and its reflection.
