Flat Mirrors

Flat mirrors are smooth flat surface covered with shiny materials . Flat mirror glass that is often seen in the form of a shiny material coated on the back side. This material is generally in the form of amalgam (mixture of silver and mercury) that are reflecting nearly all the light that falls on it.

Shadow is seen standing in front of the mirror is a sham because in the back of the mirror really is not anything. In other words , the shadow of the plane mirror is virtual image . The shadow is also seen facing the opposite direction to the direction in front of the mirror . Nonetheless , the shadow looks upright and has the same size as the object.

Thus , in general can be summarized shadow properties of flat mirrors are as follows :

1. Maya .
2. Upright .
3. Facing upside down .
4. Shadow distance equal to the distance to the mirror to mirror objects .
5. Shadow size equal to the size of objects .

Figure II.3 Sketch shadow formation process on a flat mirror

Accordance with the drawings II.3 above , then the value of So equal to the value of the Si and the value equal to the value of ho hi , so it can be formulated as follows :

So = Si ................................................ ( 2.3 )
ho = hi ................................................ ( 2.4 )
- The hi
 M === 1 ................................. ( 2.5 )
 so ho

Description :
So = the distance of objects in the mirror .
Si = the distance to the mirror reflection .
ho = height of objects .
hi = high shadows .
M = magnification of objects .
