Question

define moypia write the relationship between foca lense & radius of servation of convex lenes​

Answer 1

Explanation:

Shortsightedness is corrected using a concave (curved inwards) lens which is placed in front of a myopic eye, moving the image back to the retina and making it clearer. Longsightedness is corrected using a convex (outward facing) lens.The focal length (f) of a lens is the distance between the center of the lens and the point at which the reflected light, of a beam of light traveling parallel to the center line, meets the center line (principal axis). The radius of curvature (r) is the radius of the lens that forms a complete sphere.

Answer 2

Explanation:

Myopia means we cannot see nearby objects clearly
