1. Laws of reflection

2. Learning goals We are learning to draw images in plane mirrors.
We are learning to describe images in plane mirrors.

3. From our lab, we learned…
angle of incidence = angle of reflection

4. Specular reflection
Reflection of light off a smooth surface (ex. mirror)

5. Diffuse reflection
Reflection of light off a rough surface (ex. moving water)

6. Virtual Images
An image formed by light coming from an apparent light source
Light is not arriving at or coming from the actual image location

7. Lateral inversion
orientation of an image in a plane mirror that is backwards and in reverse order

8. How do we see the image?

10. Virtual Image
Your brain believes rays are emanating from a position behind the mirror (virtual!)

13. Properties of an Image
Use the acronym SALT

14. Reflection Worksheet Complete the worksheet
Remember that the virtual image must be the same distance from the mirror as the real object

15. Sample Question
S- same size
A- upright
L- behind mirror
T- virtual
