Question

Why do we not see an upside down image of the sun in a pinhole camera?

• A. A pinhole camera can only make point size images.
• B. Image of the sun is point size (or highly diminished).
• C. Sun is symmetric (spherical) in shape.
• D. Pinhole camera forms erect images.

Answer 1

The correct option is C Sun is symmetric (spherical) in shape.

Pinhole camera always forms inverted images only. The reason we don't see the image of the sun as inverted is that the image is symmetrical. So, erect and inverted images of the sun looks the same.
