Image formed in water is erect.

Explanation:
When an object is placed in water, the light rays from the object pass through the water and then reach our eyes. These light rays undergo refraction, which means they change direction as they pass from one medium (air) to another medium (water).

- When the light rays pass from air to water, they bend towards the normal line, which is an imaginary line perpendicular to the surface of the water.
- As a result of this refraction, the image of the object formed in the water appears to be in a different position compared to the actual object.

Image Formation:
- The image formed in water is virtual because the light does not actually pass through the image. It appears to form at the point where the refracted rays of light appear to intersect.
- The image formed in water is erect, which means it appears in the same orientation as the actual object. This is because the top of the object is still above the bottom of the object in the water, so the image appears in the same way.
- However, the image formed in water is slightly shifted from the actual object. This shift is due to the refraction of light and can be observed when looking at an object in a glass of water, for example.

Comparing to Image formed in a Mirror:
- In contrast, when an object is placed in front of a mirror, the image formed is virtual, erect, and laterally inverted. This means that the image in the mirror appears to be flipped horizontally compared to the actual object.
- The difference between the image formed in water and the image formed in a mirror is due to the different ways in which light behaves when it passes through water compared to when it reflects off a mirror surface.

Conclusion:
In conclusion, the image of an object formed in water is erect, meaning it appears in the same orientation as the actual object. This is due to the refraction of light as it passes from air to water.
