Question

what is lens and its types​

Answer 1

Answer:

A lens is a transmissive optical device that focuses or disperses light beams by means of refraction. A simple lens consists of a single piece of transparent material, while compound lenses consist of several simple lenses arranged along with a common axis.

There are two main types of lenses, known as convex (or converging) and concave (or diverging).

Answer 2

Lens

• Lenses are essentially curved-side magnifying glasses.
• A lens is a section of clear glass that focused or splits rays of light as they flow it through due to refraction.
• They are used to collect light rays and are used in cameras.
• Lenses may be used in pairs to prevent blurriness or distortion in the image created by the lens.

Types of the lens are as follows:

1. Concave Lens
2. Convex Lens
