Copy and complete the diagram below to show what happens to the rays of light when they pass through the concave lens:"

When the rays of light pass through the concave lens, they get diverge and appear to meet at the focus of the lens.


 Explanation

Diverging Lens or Concave Lens $-$ It is a lens that possesses at least one surface that curves inwards in the middle. In other words, it is thin across the middle and thick at the upper and lower edges, because of which the light that enters the lens, gets spread out, or diverges, which results in forming a smaller image. Due to this effect, it is also called a negative lens or a diverging lens.

The image formed by a concave lens is virtual & erect, which means it will appear to be farther away than it actually is, and therefore smaller than the object itself.
