11. State one property of light which is demonstrated by the working of a pinhole camera.
Answers
Answer:
The primary property of light used in a pinhole camera is that light travels in a straight line. The size of the hole matters since a hole too large will allow light from multiple angles causing the image to blur.
Answer:
The primary property of light used in a pinhole camera is that light travels in a straight line. The size of the hole matters since a hole too large will allow light from multiple angles causing the image to blur. Insert into the camera with light-sensitive side facing the pinhole. Close the lid and make sure the pinhole shutter is closed. Put the camera on a stable surface, pointing at your subject (ideally something that won't move). Slide the shutter open and start timing. In the pinhole camera, the light enters through a very fine hole and is propagated in a straight line. An inverted image is formed in a pinhole camera because the light rays coming from the top and bottom of the object intersect at the pinhole.
