Question

What is the difference in construction between a convex & concave lens with diagram​

Answer 1

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.
