A concave lens is used
to diverge incident rays
. This helps to create a virtual image on the opposite side of the refracting surface. Hence, these lenses are used in binoculars, telescopes, cameras, flashlights and eyeglasses. The images are erect and upright, unlike the real images.
What are the uses of concave and convex lens Class 10?
- It is used as Magnifying Glass.
- It is used to Make Microscope.
- It is used in spectacles to correct the vision. It cures defects called hypermetropia (far sightedness) where patients can’t see objects closer to them.

What are the two uses of concave and convex lenses?
Most high quality cameras, telescopes and binoculars use concave lenses to improve the quality of the images they provide.
Microscopes and reflecting telescopes
make use of a concave mirror, a plane mirror, and a convex lens, while refracting telescopes use two convex lenses.
What are the five uses of convex lens?
- A convex lens is employed in microscopes and magnifying glasses to converge all incoming light rays to a particular point. …
- The convex lens is used in cameras. …
- A convex lens is used for the correction of hyperopia. …
- The converging lens is used in the projector as well.

What are the uses of convex and concave lenses in daily life?
People who are suffering from farsightedness use
convex lenses in glasses to rectify their eyesight
. In cameras multiple convex lenses are used to magnify the image and to focus, followed by concave lenses. The convex lenses are used in microscopes to enlarge the sizes of the minuscule objects.
How many types of concave lenses are there?
Biconcave – A lens
in which both sides are concave is biconcave. Biconcave lenses are diverging lenses. Plano-concave – A lens in which one side is concave and the other is plano. Plano-concave lenses are diverging lenses.
What is a concave lens Class 10?
Concave lenses are thinner at the middle. Rays of light that pass through the lens are spread out (they diverge). A concave lens is
a diverging lens
. When parallel rays of light pass through a concave lens the refracted rays diverge so that they appear to come from one point called the principal focus.
What are 2 examples of a convex lens?
Convex lenses are used in microscopes,
magnifying glasses and eyeglasses
.
Who wears concave lens?
A concave lens is the opposite of a convex lens. Here one or both of the lenses surfaces are curved inwards. That is, the centre of the lens is closer to the plane than the edge. A concave lens is used
to correct short-sightedness (myopia)
.
What are concave lenses?
A concave lens is
a lens that possesses at least one surface that curves inwards
. It is a diverging lens, meaning that it spreads out light rays that have been refracted through it. A concave lens is thinner at its centre than at its edges, and is used to correct short-sightedness (myopia).
How does concave lens work?
Concave lenses
A concave lens is exactly the opposite with the outer surfaces curving inward, so it
makes parallel light rays curve outward or diverge
. … Photo: A concave lens makes parallel light rays diverge (spread out) so that they appear to come from a point behind the lens—the focal point.
What is difference between concave and convex lens?
A
convex lens is thicker at the centre and thinner at the edges
. A concave lens is thicker at the edges and thinner at the centre. Due to the converging rays, it is called a converging lens. Due to the diverging rays, it is called a diverging lens.
What are the types of convex lens?
- Plano-convex Lens: It is curved outwards from one side and the other side plane. It is positive focal length elements that have one spherical surface and one flat surface. …
- Double Convex Lens: It is curved outwards from both the side. …
- Concave-convex Lens:
