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 term indicates an image through which light does not really travel?
virtual image
Is the image viewed through the eyepiece inverted?
yes it is seen inverted
Is the image perceived through the microscope's eyepiece both vertically and laterally inverted?
yes.
Can night vision goggles see through fog?
It depends on whether the night vision goggles are image intensifiers or the type that are sensitive to infra red. Only the infra red type can see warm objects through fog. Image intensifiers will not be able to see through fog at all.
An instrument that allows light to pass through the specimen and uses two lenses to form an image is a?
The microscope.
Who created the camera?
Alhazen (Ibn Al-Haytham) He lived around 1000AD. Sometime during his life he invented the first pinhole camera, and he was able to explain why the images were upside down (I wouldn't have been able to!). The first reference to the optic laws that made pinhole cameras possible, was observed and noted by Aristotle (So many weird names!!) around 330 BC, who questioned why the sun could make a circular image when it shined through a square hole.(Good Question!!!)
How will you check if a circular linked list is empty?
image is shared
Applications of Circular convolution?
for finding convolution of periodic signals we use circular convolution
How does footage you take on a circle lens camera turn into square or rectagle when you watch it on your TV?
Good question! The image transmitted by the lens is actually circular, but it passes through a rectangular opening just before the film plane. This creates a rectangular image on the film because part of what the lens is transmitting is blocked. You are never reminded of this since the entire "previewing" system is constructed to show you what you will get, not what the lens actually "sees".
What is an image your brain perceives even through no light rays pass through the image?
A Virtual Image
Why don't cameras take round pictures?
Some might do - depends on what camera or settings they have. There are some that can. While the lens produces a circular image, it was easier to fit square or rectangular images onto a strip of film. A 35mm lens used on a large format (5x4 inch or 8x10 inch) sheet film will indeed produce a circular image in the middle of the plate. It's a criminal waste of film, though.
What can this mean in a brain teaser 1's mirror image then a square and 2's mirror image?
Back to square one.
How many faces are there on a square?
One. A square is a two dimensional image.
What is the term an image through which light passes?
real image
What is the term for an image through which light passes?
real image
What is meant by mean square error in digital image processing?
The mean square error is used as part of the digital image processing method to check for errors. Two MSEs are calculated and then compared to determine the accuracy of an image.
What is an image your brain perceives even though no light rays pass through the image?
