Question

which statement best describes the principle of the camera obscura?
a. light passing through a hole in the wall of a completely darkened room forms an image of the outside object on the opposite wall.
b. light passing through a hole in the wall of a completely darkened room forms an inverted image of the outside object on the opposite wall.
c. light entering a room will form an image of whatever lies outside on the opposite wall of the room.

Explanation:

The camera obscura principle involves light passing through a hole in a darkened room. Due to the rectilinear propagation of light, the image formed is inverted. Option A misses the 'inverted' aspect. Option C is too vague as it doesn't mention the hole and the darkened room condition.

Answer:

B. Light passing through a hole in the wall of a completely darkened room forms an inverted image of the outside object on the opposite wall.
