Answer:
A. They diverge on refraction
Explanation:
- The concave lens has the physical characteristics that both sides are curved inwardly. Due to this physical nature, the lens is thicker towards the outer circumference.
- Due to such physical characteristics of a concave lens, when parallel light rays strike on a concave lens, it is refracted and diverge out from the other side.
- When the diverging rays are traced back, it seems as if the rays are appearing from a point.
- This point is where the rays seem to appear is called the principal focus of the lens.
- Thus the image formed by the concave lens is erect, virtual and diminished.
