what is concave and convex lens
Answers
Answer:
The lens which disperses the light rays around, that hits the lenses, are called a concave lens. In the convex lens, the curve is outward facing, whereas, in the concave lens, the curve faces inward. When the light rays pass through the convex lens, it converges the light rays and focuses on one point.

Answer:
A lens is a piece of glass or other transparent material with curved sides for concentrating or dispersing light rays, used singly (as in a magnifying glass) or with other lenses (as in a telescope)
Concave lens
A lens made by joining the parts of two spherical surface that is thinner in the middle than at the edges it converts the incident parallel rays and bends away from the principal axis. hence it is a diverging lens
Convex lens
A lens made by joining the parts of two spherical surface that is thicker in the middle than at the edges. it converts the incident parallel rays and bends towards the principal axis. hence it is a converging lens
