Mirror is a thing that is never everlasting. Mirror reflects shadow that is in front of it with same shape, same color, and same detail. Many kinds of mirror’s shape that is offered by some shops have the same function, which is for reflection. It is just for reflection. Although the mirror’s shape is square, circle, oval, prism, etc. its function is just for reflection. Do not you think that is so flat? A change of the mirror’s shape occurs only in its shape and its color without any additional things.
