Question

Which of the following is the property of Concave lens is

a. It diverges the light rays

b. Forms real and inverted image

c. Thick at the centre , thin at the edges

d. It converges the light rays​

Answer 1

Explanation:

Properties of the images formed by a concave lens.

When the position of the object is in front of the concave lens, the position of the image is before the object on the same side. The image formed by the concave lens is always virtual, erect, and diminished (very small).

Answer 2

Hence, a concave lens diverges rays of light whereas a convex lens converges rays of light. So, the correct answer is option D i.e. diverges and converges. Note: The converging and diverging nature of the lens depends upon the thickness of the lens and also on the refractive index of the lens.
