Question

If the hole is much bigger i.e., equal size as flame in pinhole camera, what happens to the image?

Answer 1

The image is unseen and also not inverted.

Answer 2

According to the data mention in the question that,

If the hole is much bigger i.e., equal size as flame in pinhole camera,

The image will not form at all on the opposite side of the candle.

Because,a small and pin sized hole is required to pass the accurate amount of light rays for the formation of the inverted image on the opposite side.

That's why it is name as the "pinhole" camera.

Larger holes allow more light ray to pass through which never forms an image on the nearby screen.
