diminished and point sized?

(b) Convex mirror only

(c) Convex lens only

(d) Concave mirror, convex mirror, concave lens and convex lens​

Answer 1

Explanation:

CONCAVE MIRROR IS YOUR ANSWER

.

Answer 2

Answer:

Explanation:

A highly diminished picture is generated at the focus when rays of light from infinity hit a concave mirror, convex mirror, concave lens, or convex lens.

Concave mirror:

A concave mirror can produce real or virtual images, inverted or upright ones, and ones that are magnified or lessened depending on the object's position.

Convex mirror:

Regardless of the object's position, a convex mirror will always provide a virtual, erect, and reduced picture.

Concave lens:

• A lens type known as a concave lens has at least one side that is bent inward.
• A biconcave lens is a concave lens with two inwardly curving surfaces.
• Concave lenses spread out light rays that have been refracted through them because they are divergent lenses.
• They can cause a parallel beam of light to diverge.
• With a concave lens, either the middle is thinner than the edges or the edges are broader than the middle.
• Spectacles with concave lenses can correct myopia or short-sightedness.

Convex lens:

• A lens with an outward curve is said to be convex.
• A convex lens has a greater thickness in the middle than it does at the edges.
• Converging lenses are those that are convex. They have the capacity to focus a parallel light beam into a single point.
• One of the best examples of a convex lens is the one that is found in the human eye.
• The magnifying glass that is used to treat hypermetropia or long-sightedness is another typical example of a convex lens.
