10.3 Check and Reflect Questions 1-4, 8, 11, 12

1. The ray model of light shows the directions that the light rays travel when they're being emitted.

2. Feature not available.

3. -The directions that the rays travels.
-What objects are being affected or reflecting the light.

4.-The light can bounce off the object. 
-The light can be absorbed by the object.
-The light can be reflected by the object.

Due to Materials:
- Light can go through.
- Obscured amount of light can go through.
- No light can go through.

8.a) Diffuse reflections are reflections of light from a rough surface while regular reflection is reflection of light from a smooth surface.
b) Diffuse reflection: Light reflecting of a paper bag.
Regular reflection: Mirror

11. The ray model can show where the basketball can theoretically bounce off light so it can outline the shape of the basketball.

12.A piece of wood has a rough unpolished surface while a piece of metal has a shiny, polished, and smoother surface. As we know polished and smoother surfaces provide better reflections therefore metal would work better.
