What will happen to a image if the object moves away from a concave mirror ?...

What will happen to a image if the object moves away from a concave mirror ? Closer to the mirror? Draw ray diagrams to support your predictions.

Solutions

Expert Solution

The above shown are the ray diagrams of image formation in a concave mirror. Excluding the special case where the image is formed behind the mirror when the object is placed in between F and P, the coclusions that can be drawn are

As the OBJECT is moved CLOSER to the mirror, the corresponding IMAGE formed seems to move AWAY from the mirror, with the size of the image gradually increasing.

As the OBJECT is moved AWAY from the mirror, the corresponding IMAGE formed seems to move CLOSER to the mirror, with the size of the image gradually decreasing.
