What is lense and its types?
A lens is a curved piece of glass or other transparent material that refracts light to form an image. There are two main types of lenses: convex lenses, which converge light rays to a focal point, and concave lenses, which diverge light rays. Additionally, there are specialized lenses such as plano-concave, plano-convex, and biconvex lenses that have specific applications in optics.
What is the difference between a concave and convex lens?
Convex lenses are thicker in the middle than at the edges. They refract toward the center. Only people have convex lenses. Concave lenses are used in telescopes and glasses. Concave lenses are thinner in the middle than at the edges. When light passes through concave lenses always bend away from each other toward the edges of the lens.A convex or "positive" lens is thicker in the middle and thinner at the edges. A concave, or "negative" lens is thinner at the middle and thicker at the edges. Convex lenses project a real image behind the lens; concave lenses project a virtual image in front of the lens.
How do images formed by a concave lens and convex mirror different?
Images formed by a concave lens are always virtual, upright, and reduced in size. On the other hand, images formed by a convex mirror are virtual, erect, and diminished in size. Additionally, concave lenses can form both real and virtual images depending on the object distance, while convex mirrors only produce virtual images.
How do convex and concave lenses affect the attitude and appearance of an image?
Convex lenses converge light rays, resulting in real and inverted images for objects placed beyond their focal point. These lenses are used in magnifying glasses and cameras to produce focused images. On the other hand, concave lenses diverge light rays, creating virtual and upright images. They are commonly used in correcting nearsightedness.
Difference between convex and concave lens?
The difference between concave and convex is that convex lenses are the type of lens that make images bigger, while concave make images smaller. Still confused, maybe this will help. When you think of concave think of a cave, how you can see a small image at the end of the cave, while convex is the opposite.
How do people use lenses to see things a long way away?
Lenses are either concave or convex. Concave lenses curve inward from both sides, and convex lenses curve outward one side and inward on the other. Concave and convex lenses change the image to be able to see from close or far distances.These are used for glasses, magnifying glasses, and telescopes.

How are convex and concave different?
They have different curvatures, one curves in and the other curves out.

What things use convex lenses?
You know those microscopes? Well, you probably do. A convex lens can be found in a microscope. Concave AND convex are both used in this item. You can also check www.brainpop.com on microscopes depending on your age (3-5 grades). It sadly cost money. There are also farsightedness glasses that use convex lenses. And you might've guessed, nearsightedness glasses use concave. Magnifying glasses are of convex lens use, too. Then there's also contact lenses. Magnifying glasses, telescopes, vehicle mirrors and more mirrors in hospitals and other building use these lenses. Sorry if this paragraph was too long but I hope this was helpful!
What is the difference between convex and concave lenses?
The expressions relate to the shape of the surfaces of the lens. Concave means that the surface is like the inside of a sphere, convex means that it looks like the outside surface of a sphere. A lens has two surfaces. Most often the spectacle lens are bent away from the eye: the nearer surface is concave and the outside surface is convex.
What are examples of types of lenses?
there are two types of optical fiber,the first type is single mode fibers.the second type is multimode fibers.
What happens when light passes through concave and convex lenses?
When light passes through a concave lens, it diverges or spreads out. This results in the formation of a virtual and upright image. On the other hand, when light passes through a convex lens, it converges or comes together. This leads to the formation of a real and inverted image.
