Question

what is the between difference concave lens and convex lens.​

Answer 1

Answer: Difference Convex and Concave Lens

Explanation:

Difference Convex and Concave Lens

1. The lens which merges the light rays at a particular point, that travels through it, are a convex lens. The lens which disperses the light rays around, that hits the lenses, are called a concave lens.
2. In the convex lens, the curve is outward facing, whereas, in the concave lens, the curve faces inward.
3. When the light rays pass through the convex lens, it converges the light rays and focuses on one point. On the other hand, when the light rays go through the concave lens, it diverges the beams, i.e. they spread out.
4. The structure of convex lens is like, thicker at the centre and thinner at the edges. Conversely, the concave lenses are thinner at the centre and thicker at its edges, in structure.
5. The focal length of a convex lens is positive, while that of a concave lens is negative.
6. Generally, a convex lens forms a real image, but it can also create a virtual image when the object is in the middle of the focus and optical centre. On the contrary, the image formed by the concave lens is erect, virtual and smaller, than the object.
7. Due to the thicker centre of convex lenses, the objects are seen larger and closer. Unlike, concave lens, whose thin centre causes the object to look farther and smaller.
8. A convex lens is used to treat hyperopia or farsightedness. In contrast, the concave lens proves helpful in the treatment of myopia or short sightedness.
