How is the image affected in a pinhole camera when another fine hole is made near the first pinhole?

उत्तर
If another pin hole is made near the first pin hole, two images are formed on the screen, one due to each of the two pin holes. If the holes are very close, the two images tend to overlap each other. As a result, a blurred image will be seen.
