Question

What determines the type of the image formed after refraction from a convex lens?

Answer 1

Type of image is either real or virtual.

Real images (convex)
-light rays travel to a real image from the object

Virtual images (concave)
-not really there and no light reaches them

d. type of light source

**just an opinion, i might be incorrect

Answer 2

Answer:

Position of the object

Explanation:

What determines the type of image formed by an object in front of a convex lens is the position of the object from the lens. The nature of image formed is determined by the position of the object placed on the principal axis from the lens. As the object is moving closer to the mirror, the nature if the image formed by the object gets magnified. For example, the nature of image formed by an object on the focus will be different from the nature of image formed by an object placed between the focus and the optical center.

When object is positioned on the principal focus of the lens, the image formed will be at infinity, while that positioned between focus and optical center will produce a magnified, erect and virtual image.
