23 of 23

  1. In order to produce a VIRTUAL IMAGE with CONVEX MIRROR, an object must be placed anywhere.

  1. In order to produce the LARGEST IMAGE POSSIBLE with CONVEX MIRROR, an object must be placed close to the mirror.

​

  • In order to produce an IMAGE SMALLER THAN THE OBJECT with CONVEX MIRROR, an object must be placed anywhere.

​

  • If the OBJECT IS MOVED far away from a CONVEX MIRROR, the image will move close to the Focus.
