Why are images upside-down in a pinhole 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.
Why is the image in a lens camera brighter than the image in a pin hole camera?
Think in terms of ray tracing. Light travels in a straight line in a pinhole camerabecause there is no refracting or reflecting optical element to change the path of the rays of light. The bottom of the film is on the line passing through the pinhole and top of the object. Since all light must pass through the pinhole, that means the top of the object exposes the bottom of the film.
How does a camera use Sonar?
A camera uses sonar to detect the distance to the object you are taking a picture of so it can focus the lens properly.
What happens to the size of the image if the object is moved closer to the lens of a camera?
The size of the image has no relevance to how close or far a lens is from its target, regardless if the camera is digital or not. If the camera is set to save images at 800x600, it will still be 800x600 no matter where the lens is focused.
Why is a pinhole camera useful to your world?
Each single ray of light that reflects from a single point on an object does so in an infinite number of directions. The job of a lens is to gather and focus as many of these rays, which have slightly different angles of incidence, as possible. Since there is no lens in a pinhole camera, the method of control is to allow only a few of the rays from a single point that are close in angles of incidence to pass and land close together on the image plane. This can only be done by using a small opening.
What will happen if object distance is decreased in pinhole camera?
If the object distance is decreased in a pin hole camera, the image size will increase. If the object is too close, the full image will not be formed and the screen will appear dark.
Why is the image formed by a pinhole inverted?
An inverted image is formed in a pinhole camera because the light rays coming from the top and the bottom of the object intersect at the pinhole.

Where can I buy a good pinhole camera online?
A pinhole camera is a very tiny camera that is modified to fit an object and be hidden from plain sight. Many pinhole cameras are called "nanny cams" as they are designed to fit in a teddy bear and placed in a child's room. You can buy them online from the Total Security Store and Hub Pages.
What kind of image is formed by a pinhole camera?
Think in terms of ray tracing. Light travels in a straight line in a pinhole camerabecause there is no refracting or reflecting optical element to change the path of the rays of light. The bottom of the film is on the line passing through the pinhole and top of the object.

Why is the image upside in a pinhole camera?
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.
What happens to the size of the image if the object is moved closer to the lens of a camera?
The size of the image has no relevance to how close or far a lens is from its target, regardless if the camera is digital or not. If the camera is set to save images at 800x600, it will still be 800x600 no matter where the lens is focused.
What are 3 things that govern depth of field?
Aperture Lens focal length Subject distance (the distance from the camera to the object that has been focused on)
Why can the sun make a circular image when it shined through a square hole?
The shape of the pinhole in a pinhole camera does not matter when the object is as far away as the sun (or even the moon). I once watched a solar eclipse by watching the continuously moving shadows on the ground of the leaves of trees. The gaps between the leaf shadows showed hundreds of bright images of the eclipse.
What must happen to an object if a force does work on it?
Move a certain distance since Work Done=Fd
