if the distance between the pinhole and luminous object is reduced
Answers
Answer:
Answer
1. If the hole is bigger than a pin hole, again a blurred image in seen. The reason is that a bigger hole is equivalent to a large number of pinholes. Each pin hole produces one image. These images overlap each other resulting in a blurred image.
2. If the object is moved towards the pin hole the size of the image increases. The size of image / The size of object = Distance of screen from pin hole / Distance of object from pin hole
3. When the length of the pin hole camera is increased. C is the screen is moved away from the pinhole, the size of image also increases.
