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 always virtual, erect, and diminished (smaller than the object) regardless of the object's distance.
It is used to treat a condition called nearsightedness or short sight (also called myopia). Also, used in laser, binoculars, telescope, and flashlights.
