An object is placed at the following distance from a convex lens of focal length 15cm:
- 35cm
- 30cm
- 20cm
- 10cm
- A magnified real image?
- A magnified virtual image?
- A diminished real image?
- An image of same size as the object?

- The object should be placed at 20cm because a convex mirror forms a real, magnified image when an object is placed between f and 2f.
- The object should be placed at 10cm because a convex mirror forms a virtual, magnified image when an object is placed placed between f(focus) and the optic centre
- The object should be placed at 35cm because a convex mirror forms a real, diminished image when an object is placed beyond 2f.
- The object should be placed at 30cm because a convex mirror forms a real image of the same size when an object is placed at 2f.
