The pinhole camera works on - JAMB Physics 2023 Question
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
correct option: b
The principle of the rectilinear propagation of light.
The pinhole camera operates based on the principle that light travels in straight lines. This principle is known as the rectilinear propagation of light. In a pinhole camera, light enters through a small aperture (pinhole) and travels in straight lines, forming an inverted image on the opposite side of the camera. The process is governed by the rectilinear propagation of light. Options A, C, and D do not specifically describe the principle behind the operation of a pinhole camera.
