please answer as fast as possible
Answers
Explanation:
A pinhole camera is a simple camera without a lens but with a tiny aperture (the so-called pinhole)—effectively a light-proof box with a small hole in one side. Light from a scene passes through the aperture and projects an inverted image on the opposite side of the box, which is known as the camera obscura effect.
Answer:
1. The light ray which is coming from top of the tree goes towards the bottom of the pinhole camera screen through the pinhole.
2. The light ray which is coming from bottom of the tree goes towards the top of the pinhole camera screen through the pinhole.
3. In this way the light coming in a particular direction from each point of the tree, will be able to enter into the pinhole and the light going in other directions is blocked.
4. This leads the formation of an inverted images.
5. If we increase the size of the hole of pinhole camera, we get blurred image on the screen.
