Answer 2

Answer:

Basis for Comparison Concave Lens Convex Lens

As known Diverging lens Converging lens

Shape of the optical surface In concave lens, the centre of the glass piece is thin while the edges are thick. In convex lens, the centre of the glass piece is thick whereas the edges are thin.

Polarity of focal length Negative, thus sometimes referred as negative lens. Positive, hence another name used for it is positive lens.

Behaviour It diverges the light rays. It converges the light rays.

Presence of focal point On the side of lens from where the rays are falling. On the opposite side of the lens from where the rays are falling.

Type of image formed Always forms virtual and erect image. Generally, forms real and inverted image.

Vision defect It is used to correct Myopia It is used for the correction of hypermetropia.

View Farther and smaller than the actual entity. Nearer and larger than the original entity.

Example Lens in human eye, microscope, telescope, etc. Flash lights of vehicles, lasers and peepholes of doors.
