प्रश्न
State the effect on the image in a pinhole camera if the hole is made bigger.
उत्तर
If the hole is bigger than a pinhole, again a blurred image is seen. The reason is that a bigger hole is equivalent to a large number of pinholes. Each pinhole produces one image. These images overlap each other resulting in a blurred image.
