The main difference between the convex lens and the concave lens is that the light rays passing through the convex lens will merge at a particular point known as the focal point, while the concave lens will diverge the light rays passing through it.
Convex lens vs. concave lens
The word “lens” is derived from “lens,” that is, a Latin name for “lentil” (a plant with lens-shaped seeds). A lens is a transparent optical device that fuses or scatters light rays that pass through it by refraction. It is made of glass or plastic, etc. It is widely used in microscopes, telescopes, cameras, and even to correct vision problems, etc. Depending on the shape, convex and concave lenses are two types of lenses. A convex lens is the lens that will fuse the light rays passing through at a specific point, while the light rays passing through the concave lens will diverge.
what is the difference between convex and concave lens?
|It is defined as the lens that fuses the light that passes through it at the focal point.
|It is defined as the lens that diverges the light that passes through it.
|This lens is thicker in the center and thinner around the edges.
|It is thicker at the edges than in the center.
|The object will appear closer and larger.
|The object will appear smaller and beyond.
|The image will be real and reversed.
|The image will be erect, virtual and diminished.
|Both the image and the object are on the same side of the lens.
|The object is on one side of the lens while the image is on the other side.
|The position of the focal point
|In front of the lens
|On the back of the lens.
|Its focal length is positive.
|Its focal length is negative.
|Use it to correct hyperopia
|Use it to correct myopia.
|It is used as a camera lens.
|It is used as a vehicle side mirror.
- A convex lens is a lens that converges the light rays that pass through it at the focal point, while the concave lens is the lens that diverges the beam of light that passes through the lens.
- Convex lens bent outward while concave lens is bent
- A convex lens has thin edges, while the concave lens is thinner in the center.
- The real and inverted image is formed through the convex lens, but a concave lens forms an erect, virtual, diminished image.
- The focal length of the convex lens is positive while that of the concave lens is negative.
- A convex lens is used to deal with myopia, while the concave lens is used to deal with hyperopia.
- Through the convex lens, the object will appear closer and larger while the concave lens shows the object smaller and further away. convex and concave lens
According to the previous discussion, it is concluded that the convex lens is a lens that converges the light rays that pass through it and forms a real and inverted image of the object while the concave lens diverges the light beam and forms an erect image, virtual and diminished. of the object.
Concave and Convex Lenses Frequently Asked Questions (FAQ)
- Do the cameras use convex or concave lenses?
A camera generally has a convex lens, but for higher quality purposes, convex and concave lenses are used.
But it would be wrong to say that the camera uses a concave lens since the main lens is convex.
For a higher quality purpose, a concave lens is used with a convex lens. Basically, it depends on the type of camera and the lens that was used. convex and concave lens
- What lens is present in the human eye?
The lens, which is present in the human eye, is convex. Helps the retina focus on refracted light for clear vision.
- What kind of image is formed by a convex lens?
A convex lens can form real, infinite, or virtual images. For example: when an object appears larger from the lens than the focal length, the image will be real.
When the object is equal to the focal length, the image will be infinite.
When an object appears below the focal length of the lens, the image will be vertical or virtual. convex and concave lens
- What kind of image does a concave lens form?
The concave lens forms small virtual images. If you place an object at a distance that appears greater than the focal length, the image appears small or reduced in size.
- How is a convex lens made?
A convex lens is made of clear plastic or glass. A convex lens has a surface that curves outward.
A convex lens is generally used for binoculars or telescopes, which make objects clear, even at a distance.
A convex lens is also very helpful for treating hyperopia or hyperopia. convex and concave lens
- How is a concave lens made?
A concave lens is made of glass or also clear plastic.
The surface of a concave lens is curved on the inside. Produces smaller images for the viewer by spreading the light.
They are used in flashlights and lasers in CD and DVD players.
A concave lens is also used in the treatment of nearsightedness or nearsightedness.
Concave and convex lenses are used to produce clear and sharp images. They are used in various experiments and most eyeglass lenses are a combination of these two lenses. Telescopes, cameras, and lenses have brought about a revolutionary change in the world.
People can now perceive things differently, and this world has become colorful and beautiful. Both concave and convex lenses generate different types of images and have a wide range of applications in the real world.
There are significant differences between the two and these differences are important. Therefore, if one wishes to work with lenses, knowing the similarities and differences is crucial as it can get in the way of working with lenses. convex and concave lens
