Question

Differentiate between concave and convex lens. (3)

Answer 1

Answer:

Difference between Concave and Convex Lens. A convex lens or converging lens focuses the light rays to a specific point whereas a concave lens or diverging lens diverges the light rays. A lens is a transparent material (either curved or flat surface) based on the principles of refraction.

Answer 2

Answer:

in the convex lens the curve is outward facing whereas in the cancave lens,the curve faces inward

when the light ray passes through the convex lens,it converges the light rays and focussed on one point.

conversely the concave lenses are thinner at the centre and thicker at its edges , in structure
