Difference Between Concave and Convex Lens

Edited By Team Careers360 | Updated on May 27, 2022 05:55 PM IST

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.

NCERT Physics Notes :

Difference between convex and concave lens

Properties	Concave lens	Convex lens
Look	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	Negative	Positive
Incident rays	The incident rays are diverged away from the main axis.	The incident rays are converged towards the primary axis.
Applications	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.

Frequently Asked Questions (FAQs)

1. How does a concave lens differ from a convex lens?

The type of opposite facial curve determines the difference between concave and convex lens. It also identifies the type of recurrence in making it.

2. How can I memorize an example of a concave lens?

If you follow the summary section of this page, you will find the use of this lens described in the simplest version. You can easily memorize lens applications.

3. What is the main difference between concave and convex lens?

Basically, the bright spot of the convex mirror shapes on the outside while the concave mirror goes inside. The main difference is the image we create in these two mirrors. In other words, thin images from convex mirrors while enlarged images from concave mirrors.

4. How to find out if a shape is concave or convex?

The difference between the concave and convex lens lies in the months of their given angles. For a polygon to be exposed, all of its internal angles must be less than 180 degrees. Otherwise, the polygon is concave.

5. Is the rhombus concave or convex?

A rhombus with interlocking sides can have sides measuring about four inches in length. A square is a parallelogram with four interlocking angles (right angles) and four interlocking angles, and has all the properties of a parallelogram, rectangle and rhombus. Parallelograms are convex quadrilaterals

6. What does a convex look like?

As concave, convex can be used as a local name or a line that turns outwards, and has the use of geometry, in which it describes a polygon with internal arms less than or equal to 180 °.
