Question

A pinhole camera produces image because of the propagation of light.

• A. curvilinear
• B. rectilinear
• C. virtual-erect
• D. real-inverted

Answer 1

Answer: (B), (D)

real-inverted

In a pinhole camera, light rays from an object passes through the pinhole and forms an image on the screen. Also, light travels in a straight line (rectilinear propagation), so the light rays which come from the top of the object goes straight towards the bottom of the screen and light rays which come from the bottom of the object goes straight towards the top of the screen. Thus, it forms a real and inverted image of the object.
