Image formation by Convex and Concave Lenses

The concave and convex lenses are the spherical lenses that are bounded by two spherical transparent surfaces. The concave lens is made by binding together two transparent spherical surfaces which are curved inward while the convex lens is made by binding together two transparent spherical surfaces which are curved outward. Here we have explained how the image is formed by both the lens concave and convex.

Image formation by Concave Lens:

When an object is placed at infinity: The incoming parallel rays strike the lens then the concave lens diverges them resulting in the formation of a virtual image at the focal point of the concave lens.

image formed by concave lens when object is at infinity

When an object is placed at a finite distance: The incoming parallel rays strike the lens then the concave lens diverges them, since the object is near to the lens therefore some of the incoming rays pass through the optical centre which results in the formation of the image between optical centre and focal point of the concave lens. The size of the image

Image formation by Convex Lens:

When an object is placed at infinity: The incoming parallel rays strike the lens then the convex lens converges them to its focal point resulting in the formation of a real and pointed image at the focal point of the convex lens.

When an object is placed at the point beyond the centre of curvature(2F1): When an object is placed beyond the centre of the curvature, then a parallel beam of the light strikes the lens and passes through the focal point after refraction. A beam of light also passes through the optical centre consequently image is formed between the centre of the curvature and the focal point.

When an object is placed at the point beyond the centre of curvature: When an object is placed at the centre of the curvature, then a parallel beam of the light strikes the lens and passes through the focal point after refraction. A beam of light also passes through the optical centre consequently a real image of the same size is formed at another centre of the curvature.

When an object is placed between the centre of curvature and focal point: When an object is placed between the centre of curvature and focal point, then a parallel beam of the light strikes the lens and passes through the focal point after refraction. A beam of light also passes through the optical centre consequently a real image of the size larger than the object is formed behind the centre of the curvature.

When an object is placed at a focal point: When an object is placed at the focal point, then a parallel beam of the light strikes the lens and passes through another focal point after refraction. A beam of light also passes through the optical centre consequently a real image of a much larger size is formed at the infinity.

When an object is placed between focal point and the optical centre: When an object is placed between the focal point and the optical centre, then a parallel beam of the light strikes the lens and passes through another focal point after refraction. A beam of light also passes through the optical centre consequently a virtual image of larger size is formed behind the centre of the curvature.
