Answer 1

Answer:

1.A convex lens is thicker at the centre and thinner at the edges. A concave lens is thicker at the edges and thinner at the centre. Due to the converging rays, it is called a converging lens. Due to the diverging rays, it is called a diverging lens.

2.Lenses serve to refract light at each boundary. As a ray of light enters a lens, it is refracted; and as the same ray of light exits the lens, it is refracted again. ... Because of the special geometric shape of a lens, the light rays are refracted such that they form images.

3.Convex lens is used in microscopes and magnifying glass.

Convex lens is used as a camera lens in cameras.

The convex mirror is used as side-view mirror.
