The image formed by the pinhole camera on the screen is real and inverted. Light changes its direction after reflection. As we move the object away from the light source, the shadow becomes larger as the distance between object and the light source increases. Irregular reflection occurs from a rough surface.

Explanation:
Pinhole Camera Image:
- The image formed by a pinhole camera is inverted because light travels in a straight line.
- In a pinhole camera, light rays pass through a small hole and create an inverted image on the opposite side. This happens because light travels in straight lines and the image is formed where the light converges.
Light Reflection:
- Light does change its direction on reflection.
- When light hits a surface and reflects off it, it changes its direction. This is why we can see our reflection in a mirror or any other polished surface.
Shadow Size with Object Distance:
- As we move the object away from the light source, the shadow of the object becomes larger, not smaller.
- The size of a shadow is directly proportional to the distance between the object and the light source. So, as the object moves away from the light source, the shadow it casts becomes larger.
Reflection Surfaces:
- Reflection is possible not only from polished surfaces but also from rough or irregular surfaces.
- Any surface that is not transparent or opaque can reflect light to some extent. Polished surfaces provide clearer reflections, but other surfaces can also reflect light.
