Question

A stereoscope provides the illusion of depth in 2-d images by _____.​

Answer 1

Step-by-step explanation:

Stereoscopy is the production of the illusion of depth in a photograph, movie, or other two-dimensional image by the presentation of a slightly different image to each eye, which adds the first of these cues (stereopsis). The two images are then combined in the brain to give the perception of depth.

Answer 2

A stereoscope uses two pictures from slightly different viewpoints in order to provide the illusion in 2-d images. The two slightly different pictures of the same object or scene will be seen by the left eye and the other picture will be seen by the right eye, and then when they are viewed in stereoscope, the two pictures were fused perceptually into single image containing depth.
