Question

Name the geometric shape modeled by a pinhole in the wall.

a) Square
b) Circle
c) Triangle
d) Cone

Answer 1

A pinhole models the geometric shape of a cone, as light creates a conical form when it passes through a small aperture.

Step-by-step explanation:

The geometric shape modeled by a pinhole in the wall is represented by a cone. When light passes through a small pinhole, it spreads out in all directions from the point of the pinhole, forming the shape of a cone.

This is consistent with the concept of conic sections which are formed by the intersection of a plane with a cone, and can be identified as circle, ellipse, parabola, and hyperbola. The correct answer to the question is d) Cone.
