Question

Can convex lenses give diverging rays?

Answer 1

Hint: The converging lens is defined as the lens in which light rays enter it parallel to its axis cross one another at a single point on the opposite side with a converging effect. If the refractive index of the material of a medium is made using materials that have a lower refractive index than the surrounding so it is possible in specific circumstances.

Complete step by step answer:

Focal Point\[F\]:
The focal point \[F\] of the lens is defined as the point at which the light rays cross.
Focal Length\[f\]:
The focal length is defined \[f\] as the distance from the center of the lens to its focal point.
In the given figure, Rays of the light entering a converging lens parallel to its axis converge at its focal point \[F\]. Ray \[2\] lies on the axis of the lens. The distance from the center of the lens to the parallel to the focal point is the lens focal length\[f\]. The ray \[1\] shows perpendiculars and the angles of incidence and refraction at both surfaces.
All the light rays entering parallel to its axis cross one another at the single point on the opposite side of the lens and the lens is defined as a converging lens or convex lens for the converging effect it has on light rays.
As an expanded view of the path of a one ray through the lens to illustrate how the ray changes direction both. It enters and it leaves the lens. The index of the refraction of the lens is greater than that of air when the ray moves towards the perpendicular as it enters. It away from the perpendicular as it leaves. This is in accordance with the law of refraction. The lens’s shape, light is bent toward the axis at both surfaces.
In conclusion, the convex lens gives diverging rays in some specific circumstances.

Note:
Convex lenses are thicker at the middle and a convex lens is a converging lens.
The principal focus is defined as when parallel rays of light pass through a convex lens the refracted rays converge at one point.
An air bubble in water is like a converging lens and acts as a diverging lens.
