Answer 1

Explanation:

The lens which bounded by two spherical surface curved inward is CONVEX LENS.

Thank you

Answer 2

Answer:

A lens which is bounded by two spherical surfaces curved inward is called the concave lens.

Explanation:

• In order to concentrate a straight light beam into a distorted, upright virtual image, a concave lens must first bend the beam away from the source.
• It can produce real-world and digital images. Concave lenses show the presence of at least one curved interior surface.
• A concave lens is also known as a diverging lens because it causes the light to diverge; it is rounded at the centre and bulges outward at the edges.
• Since they make distant objects appear smaller than they actually are, they are used to cure myopia.
• Similar to plano-concave lenses, bi-concave (double-concave) lenses cause collimated incident light to diverge by having an equal radius of curvature on both sides of the lens.

Thus, A lens which is bounded by two spherical surfaces curved inward is called the concave lens.
