Difference between Concave and Convex Lens

Difference between Concave and Convex Lens

Light is an interesting chapter included in the science syllabus. Students learn many new concepts in this chapter. As they move through the new stages, they dig deeper into the basic and advanced ideas of light. First, they study the characteristics of light rays and then proceed to learn what light rays are. As they progressed further, they learned how light emissions occur in the visible realm. We will learn about the features of a concave and convex lens in this section.There are usually two types of lenses, namely concave and convex lenses. The shape of the curved area determines the type of lens. A study of lens performance will help the difference between concave and convex lens.

What is Convex Lens?

The transparent curved wire made of glass that looks like part of a composite area is called a convex lens. The surface of the lens has an outer curve that looks like a glass ball face. When bright light falls on the surface of the lens, it tends to appear in its paths.

When both are naturally occurring, they are called the biconvex lens. When parallel rays fall on the surface of the lens, they tend to combine and combine in one place. This point is called lens focus. Focus length is measured by the focal point of the centre of the lens. The focus point is also called the main focus of the lens. The sixth law of the integrated lens regarding image formation governs the size and quality of images. This lens is used in a variety of ways.

Use of Convex lens

Convex Lens can be formed from microscopes, to magnify glasses and eyeglasses. They are also used in cameras to create realistic images of distant objects. The quality of the images depends on how well the lenses are used. The main reason to study the use of convex lenses is to find out how light reflectors are used to see things clearly.

The above example of convex lenses shows how these lenses are used to create realistic images to achieve a purpose. In eyeglasses, convex lenses stay close to the eyes forming a visual image. You will also learn why sculptures are real or and how they are used for a variety of purposes.

Examine the use of a light lens and find out how the lens is used to achieve a purpose. All uses will explain how lenses are used in a variety of ways. It will help you to remember the features of the lens.

What is Concave lens?

A concave lens is a type of transparent object made of glass with one or two concave positions. The best way to see a concave lens is to look at a curved area. It resembles the inside of an empty hole, almost like the mouth of a cave. These lenses are also called differentiated lenses as the occurrence of the same bars on their faces tends to deviate from their paths.

Difference between convex and concave lens


Concave lens

Convex lens


The middle of a concave lens is thinner, while the edges are thicker.

The middle of a convex lens is thicker than the edges, while the margins are thinner.

Also known as

Diverging lenses

Converging lenses

Focal length



Incident rays

The incident rays are diverged away from the main axis.

The incident rays are converged towards the primary axis.


Used in glasses, some telescopes, and door spy holes, among other things. It's also utilised to remedy a problem with short-sightedness.

Used in cameras, overhead projectors, projector microscopes, basic telescopes, magnifying glasses, and other devices. It can also be used to correct a long-sightedness condition.
