Answer 1

Answer:

Convex lens Concave lens

1.Convex lens can form both real and virtual images. Concave lens always forms a virtual image.

2.It can form magnified image. Image is always diminished in size.

ANSWER

$\huge\fcolorbox{blue}{green}{Convex lens}$

• An optical lens is generally made up of two spherical surfaces.

• If the surfaces of the lens are bent outwards, the lens is called a convex lens or biconvex lens.

• A convex lens converges a straight beam of light and is thicker at the center and gets thinner as we move towards the edges..

$\huge\fcolorbox{blue}{green}{Concave lens}$

• A concave lens is a type of lens that diverges a straight light beam coming from the source to a diminished, upright, virtual image is known as a concave lens.

• It can form both real and virtual images. Concave lenses have at least one surface curved inside
