What happens to image while we increase the size of hole of pinhole camera
Answers
Pinhole cameras use the principle of rectilinear propagation of light. When you place an object in front of the pinhole camera, a clear image is formed on the screen. The image formed on the pinhole camera is inverted. Since the aperture of the pinhole camera is small (a diameter close to 5mm) only one ray from each point on the object passes through the pinhole and moves on to the screen. Thus there is one-to-one correspondence between the points on the object and the points on the screen.
If the distance between the pinhole and screen is reduced, the size of the image will decrease and the image will become bright since the light spreads over a small area. If the distance between the pinhole and screen is increased, the image size will increase and the image however will get less bright since the light spreads over a large area.
Explanation:
when the length of the pinhole camera is increased then at that time the pinhole is not affected by the size and shape of the image but if the image if what if the pinhole camera is moved away from the screen then the image will become less bright and when it will become less bright it will also be large in size as because the density of the light will increase as a point source is moved away from the object in this case what is dancer
