Small Holes Imaging Courseware
A plate with a small hole is placed between the screen and the object, and an inverted image of the object will form on the screen. We call this phenomenon 'small hole imaging.' When the plate in the middle is moved forward or backward, the size of the image on the screen will also change. This phenomenon illustrates the property of light traveling in a straight line.
Experimental Objective: Why is the image formed by a small hole inverted? What factors are related to the size of the image? What factors are related to the clarity of the image?
Experimental Report: When the aperture is relatively large, the light rays emitted from different parts of the object will overlap on the screen, resulting in an indistinct image. As shown in the diagram (click to enlarge), if the aperture is quite large, the light rays from the A part of the object will reach point C on the screen, and the light rays from the B part will also reach point C, leading to an overlap of the light rays, causing confusion in the light information and preventing the formation of an image. The reason we cannot see an image on a piece of white paper facing the object is not because there are no light rays from the object on the white paper, but because the light rays from different parts of the object overlap on the white paper.
