As you move the green objects on the left, you can observe the images that appear on each mirror.
Mirrors can be turned into convex, concave, or flat mirrors.
You can move the object, change the size of the object, or change the focal length of the mirror.
When the grid paper is displayed, the distance from the mirror to the object and the distance from the mirror to the image can be compared.
You can press the zoom button to look at the mirror from a distance.
When you look at the mirror from a distance, if you increase the focal distance as much as possible, you can see that it is similar to a flat mirror.
