What happens if an object is placed at the focal point

A double convex lens, or converging lens, focuses the diverging, or blurred, light rays from a distant object by refracting bending the rays twice. This double bending causes the rays to converge at a focal point behind the lens so that a sharper image can be seen or photographed.

Why are concave reflections upside down? If it goes into a spoon, which is concave — going inwards — the light comes back to you at an angle. The top of the spoon will reflect downwards and the bottom of the spoon will reflect upwards. The left side of the spoon will reflect right and vice versa.

Are all mirror images the same size as the object? In geometry, the mirror image of an object or two-dimensional figure is the virtual image formed by reflection in a plane mirror; it is of the same size as the original object, yet different, unless the object or figure has reflection symmetry also known as a P-symmetry. Why are images inverted in a mirror?

The image of everything in front of the mirror is reflected backward, retracing the path it traveled to get there. Nothing is switching left to right or up-down.

Instead, it's being inverted front to back. That reflection represents the photons of light, bouncing back in the same direction from which they came.

How do you tell if a lens is converging or diverging? Whatever the mix of surfaces, if the lens is thicker at its center than its edges it is called a converging lens having positive focal length. If it is thinner at its center than its edges it is called diverging having negative focal length.

Then altering the object distance to values less than one focal length produces images that are upright, virtual and located on the same side of the lens as the object. Finally, if the object distance approaches 0, the image distance approaches 0 and the image height ultimately becomes equal to the object height. These patterns are depicted in the diagram below. Eight different object locations are drawn in red and labeled with a number; the corresponding image locations are drawn in blue and labeled with the identical number.

Only a converging lens can be used to produce a real image; and this only occurs if the object is located at a position of more than one focal length from the lens.

A converging lens will only produce a virtual image if the object is located in front of the focal point. A converging lens is sometimes used as a magnifying glass. Explain how this works; specifically, identify the general region where the object must be placed in order to produce the magnified effect. A converging lens produced a virtual image when the object is placed in front of the focal point. For such a position, the image is magnified and upright, thus allowing for easier viewing.
