Title: Mirror Image 05/10
TOE: Why is this happening?????

3. CWK
REFLECTION
We will:
Identify how lights reflects off a rough and smooth surface
Describe the relationship between the angle of incidence and the angle of reflection
Key Words: Incidence, Reflection, Virtual, Plane

4. What is happening in this video??

5. See, Think, Wonder
Why is this happening?????

6. Identify how lights reflects off a rough and smooth surface (L4+)
Mirror Image
A PLANE mirror is smooth and flat, which reflects light evenly.
This means the reflection we see looks the same as the object.
Identify how lights reflects off a rough and smooth surface (L4+)

7. Angle of Incidence = Angle of Reflection
Ray of light going IN to the mirror is the INcidence ray.
Ray of light which comes out of the mirror is the reflected ray.
Describe the relationship between the angle of incidence and the angle of reflection(L6)

8. The BIG Mirror

9. RULES OF REFLECTION
Fill in the missing words from the red box below
Angle of Incidence is equal to the angle of
The image is the same as the object
The image is the same from the mirror as the object
In the image, left is and right is We call this Inverted
The image appears to be behind the mirror, so we call this
Distance, Reflection, Left, Right, Size, Laterally, Virtual

10. Reflection Ray Box Experiment
AIM: To test the relationship between the angle of incidence and the angle of reflection.
RESULTS TABLE:
CONCLUSION: What do your results tell you?
Angle of Incidence
Angle of Reflection 10 20 30 40 50 60
Conduct a practical activity to demonstrate this relationship (L7)

11. Homework
Bring in evidence that you have started to research different eye conditions for your project. Due in: Wednesday 12th October
