Concave mirror

Have you ever looked at yourself in a spoon and noticed how the image looks bigger and upside down? That's because the spoon is shaped like a concave mirror!

A concave mirror is a special kind of mirror that bulges inward like a cave. When light reflects off an object and hits the surface of the concave mirror, the mirror bends or "reflects" the light so that it meets at a point in front of the mirror. This point is called the focal point.

Depending on how far away the object is from the mirror, the image that is formed either becomes bigger or smaller than the original object. When the object is closer to the concave mirror, the image that is formed will be bigger than the original object. When the object is farther away from the concave mirror, the image that is formed will be smaller than the original object.

So, concave mirrors can be used to magnify objects or make them appear smaller. They are used in things like telescopes, spotlights, and even makeup mirrors to help us see objects more clearly or in more detail.
