What is a difference between concave mirror and concave lens?

A concave mirror converges light rays to a focal point, while a concave lens diverges light rays away from a focal point. Concave mirrors are used for focusing light, such as in telescopes and makeup mirrors, while concave lenses are used for dispersing light, such as in correcting nearsightedness.


What is the property of image formed by concave lens?

Image formed by a concave lens or a diverging lens is virtual,upright and smaller than the object.It is used by short sighted people.


What lens has a thinner middle than the edges?

A concave lens has a thinner middle than the edges. This causes light rays passing through the lens to diverge, which is why concave lenses are often used to correct vision problems like nearsightedness.


What is the diff of concave and convex lens?

A concave lens is thinner at the center than at the edges and causes light rays to diverge. This lens is used for correcting short-sightedness. In contrast, a convex lens is thicker at the center than at the edges and causes light rays to converge. This lens is commonly used in magnifying glasses and camera lenses.


How are concave lens and convex lens different?

Concave lenses are thinner in the middle and thicker at the edges, causing light rays passing through them to diverge. This type of lens is used to correct nearsightedness or myopia. Convex lenses are thicker in the middle and thinner at the edges, causing light rays passing through them to converge. These lenses are used to correct farsightedness or hyperopia.

What is a concave lens?

A concave lens is a lens that is thinner at the center and thicker at the edges. It is used to correct myopia (nearsightedness) by diverging light rays before they enter the eye, thus helping to focus the image on the retina. Concave lenses are often used in glasses or contact lenses for people with nearsightedness.


What is a convex and a concave lens?

CONCAVE LENS : lens that atleast possess one end inwards is called as concave lens. CONVEX LENS : lens that atleast possess one end outwards like the exterior of the sphere is called convex lens. According to the medical values convex lens are used for long sight vision problem and concave lens for short sight vision problems.


What is convexo-concave lens?

A convexo-concave lens is a lens that has one side convex (outward bulging) and the other side concave (inward curving). This type of lens can be used to correct myopia (nearsightedness) by diverging light rays entering the eye.
