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

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+)

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)

The BIG Mirror

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

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)
