Playing with Physics: Image — inverted and straight!

They might just be an external form of a thing or art, but images — they form a living embodiment of our memories. They do wonders to our life.

But have you ever wondered how an image is formed? Ever bothered to indulge in the science behind the straight and inverted concept of images?

An image can be perceived in multiple ways depending on the reflexive medium chosen. A mirror produces a straight image where as other mediums produce an inverted image. But the science behind it is quite intriguing.


The following cases will depict the science behind the images perceived through different mediums:

Straight Image (Mirror Image)

The straight image is an optical effect which is formed after reflecting from substances such as a mirror. It is a concept of geometry and can also be used as a conceptualization process for 3D structures.

In this picture, the image of the pot reflecting in the mirror is straight because the picture shown in the plane mirror, is a reflected duplication of an object that shows up almost identical, however, is turned around in the direction opposite to the mirror surface.


Inverted Image( Real Image)

The inverted image is formed by the concave mirror, only if the object is placed further away.

In the above picture, the image of building is inverted because water plays the role of concave mirror. Since the object (building) is placed away from the focal point, the image here is inverted.



Spoon is defined in both ways. As it depicts concave (inverted image) as well as convex images (straight image).

The above picture, clearly explains the theory that if we place an object on the convex side of the spoon, then the image will be seen as a straight image however, when we place an object on the opposite side of the spoon (i.e, the concave side) then the image will be seen as an inverted image.
