question 1\nthis is a sketch of a ...\nheliographic\ncamera obscura\nsilhouette box\nburning box

Brief Explanations:

A camera obscura is a darkened box with a small hole through which light passes, projecting an inverted image of the outside scene onto the opposite side. The sketch shows light from a candle (A) passing through a hole and creating an image inside the box at B, which is characteristic of a camera obscura. A heliographic device uses sunlight for signaling, a silhouette box is for creating silhouettes, and a burning box is not a standard optical - related term in this context.

Answer:

B. Camera Obscura
