You would be better off to Google this and look for an image as it is tough to put in writing. However, I'll try. Light reflects in all directions from each point of an object. Imagine how a single light ray from the top of an object on the left travels to your right towards the pinhole camera aperture that is placed at 1/2 the object's height. The only rays that will make it through are going in a downward direction at an angle. They will reach the film surface but will be at the bottom of the camera. Conversely, rays from the bottom of the object will act the same, but in an upward angle of direction. They will reach the film but be at the top of the camera. Hence the image is inverted. If that is too hard to picture, the letter X is a good example of how this works - or as I said, Google it.
It would be upside down
You can - use a pinhole camera ( or viewer).
The image will be formed upside-down and reversed horizontally on the back of the inside of the camera.
You can figure out why an image in a pinhole camera is upside down if you think about how the light travels to get to the image. Light from an object higher (or the top of the object) than the camera travels in a straight line down to the camera. It goes through the pinhole and continues heading down until it hits the back of the camera. This means that the image of something higher than the camera is now low in the image. The opposite is true for light from an object lower than the camera (or the bottom of the object): it travels to a point higher in the image. Still does answer my question, how did the image get upside down? answer was no concusive.
Yes, the image on the screen of a pinhole camera is upside down because of the way light passes through the small aperture and projects onto the film or sensor inside the camera. It is a characteristic of pinhole cameras due to the nature of how light travels through a small hole.
I think a pinhole camera is similar to the human eye because like the pinhole camera when it sees something it reflects the image but it is an inverted image. With the human eye the brain corrects it and turns it the right way up. The pinhole cameras image is not corrected because it does not have a lens.
No
Pin holiday camera light travels in straight lines
A pinhole camera works by allowing light to pass through a small hole (the pinhole) and project an inverted image onto a surface inside the camera. The image is then captured by the surface, such as film or a digital sensor, creating a photograph.
The image formed on the screen of the pinhole camera is inverted because the aperture, which is a small hole, bends the light that enters the camera. This basically shows that light travels in straight line.
the image distance will appear the same
Make the hole smaller.
