The pinhole camera works on
A
the principle of the reversibility of light
B
the principle of the rectilinear propagation of light
C
Huygen’s principle
D
the principle of total internal reflection of light
Verified Correct Answer: B.
Physical Principles & Numerical Solution
The pinhole camera works on the principle of the rectilinear propagation of light. This principle states that light travels in straight lines. When light passes through the tiny hole in a pinhole camera, it forms an inverted image on the opposite side of the camera. The size of the image depends on the distance between the object and the pinhole.
