Question

Why cannot we see upside down image of the sun through a pinhole camera?

• A. A pinhole camera can only make point size images.
• B. An object like the sun which is infinite in size, forms point size or highly diminished images.
• C. Sun is spherical in shape and symmetric.
• D. The screen of the pinhole camera is inverted.

Answer 1

The correct option is C Sun is spherical in shape and symmetric.

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