As the distance of the object from the lens increases,what happens to the image size?

Smaller, smaller, smaller.

When the distance of an object from a lens increases, the image size can vary depending on the type of lens used. Let's consider two common types: convex (converging) lenses and concave (diverging) lenses.

1. Convex (Converging) Lens:
- If the object is placed beyond the focal point (F) of a convex lens, the image formed will be real, inverted, and smaller in size compared to the object.
- As the object moves closer towards the lens while remaining beyond the focal point, the image will continue to be formed on the opposite side of the lens, but it will become larger in size.
- If the object is moved between the focal point and the lens, the image will become virtual, magnified, and upright.

2. Concave (Diverging) Lens:
- When an object is placed in front of a concave lens, the image formed will always be virtual, upright, and smaller in size than the object.
- As the object moves closer towards the lens, the image will move closer to the lens as well, but it will still remain virtual and smaller in size.

In summary, for a convex lens, as the object moves closer while remaining beyond the focal point, the image becomes larger. For a concave lens, as the object moves closer, the image remains smaller.
