What occurs to the shape of the image of a point source when projected by a pinhole?
Understand the Problem
The question is asking about the effect of a pinhole projection on the shape of an image produced by a point source. It requires understanding of optics and the behavior of light as it passes through a pinhole.
Answer
The image is upside down and flipped left-to-right.
When light from a point source passes through a pinhole, it creates an image that is upside down and flipped left-to-right. This occurs because the pinhole projects an inverted image of the light source onto the other side.
Answer for screen readers
When light from a point source passes through a pinhole, it creates an image that is upside down and flipped left-to-right. This occurs because the pinhole projects an inverted image of the light source onto the other side.
More Information
The phenomenon is due to the camera obscura effect, where light enters through a small hole and projects an inverted image on the opposite side.
Tips
A common mistake is to think the image will only be flipped in one direction. Remember, it is both upside down and reversed left-to-right.
