Question

In the pinhole camera, the light rays from the source are moving through the pinhole and incident on the white screen. This is due to :

• A. the property of light called "rectilinear propagation of light"
• B. the property of light called "interference of light"
• C. the property of light called "diffraction"
• D. the property of light called "dispersion"

Answer 1

The correct option is A the property of light called "rectilinear propagation of light"

In a pinhole camera, the light rays pass through the small hole of the camera and incident on the white screen, kept on the other side of the source. This is possible because light travels in a straight line, which is known as the rectilinear propagation of light.
