Answer 1

Answer:

a type of lens with thickness (distance from the optical Axis between the two surface of the lens )that is negligible will be compared to the radius of curvature of the lens surface.

concave lens is also known as diverging lens it diverges the light Ray's

it focuses light ray to the specific point

Answer 2

If the thickness of the lens is much smaller than the diameter of the lens, we call it a thin lens.
