The kinds of Mirror

• Plane Mirror
• Concave Mirror
• Convex Mirror

1. Virtual / not real
2. The object distance to the mirror is equal to the distance of shadow to the mirror (s=s’)
3. The height of the object is equal to the height of the shadow (h=h’)
4. The magnifying of the shadow (M) is equal to 1 (M=s’/s = h’/h = 1
5. The left side of object becomes the right side of the shadow and vice versa
   

Light Reflection of Concave Mirror
There are 3 special rays,

1. The incident ray that is parallel to the focal axis is reflected to the focus point
2. The incident ray which comes through the focus point is reflected parallel to the focal axis
3. The incident ray which comes through the center point of curvature mirror will be reflected back to the curvature mirror center point
   
   
   
   

Light Reflection of Convex Mirror
There are 3 special rays,

1. The incident ray which is parallel to the focal axis will be reflected as if from the focus point.
2. The incident ray which goes to the focus point will be reflected parallel to the focal axis.
3. The incident ray which goes to the curvature focus point mirror will be reflected as if from the curvature focus point.
