Convex Lens is Converging

A real image is illustrated below. The advantage of this arrangement is that the rays of light emerging from the eyepiece dubious discuss are converging.

It uses a convex lens as the eyepiece instead of Galileos concave one.

. The Keplerian telescope invented by Johannes Kepler in 1611 is an improvement on Galileos design. The image formed by a convex lens is real. This lens formula is applicable to both the concave lens and convex lens.

Therefore when parallel light rays pass through the lens the refracted rays converge at one point called the principal focus. If this equation shows a negative -ve focal length then the lens is a diverging lens rather than the converging lens. Real images occur when objects are placed outside the focal length of a converging lens or outside the focal length of a converging mirror.

Ray tracing gives the position of the images by drawing one ray perpendicular to the lens which must pass through the focal point and a second ray that passes through. When the converging convex lens is placed in the front of his eyes it is used as a magnifying lens and makes the images large and wide. If the equation shows a negative -ve image distance then the image is a virtual image on the same side of the lens as the object.

The angle at which the rays of light enter the convex lens depends on the distance of the object from the lens. An ice cube mass 30 g at 0C is left sitting on the kitchen table where it gradually melts. A convex lens is a converging lens.

Also the converging lens makes the images virtual and erect. This allows for a much wider field of view and greater eye relief but the image for. A convex lens converges the light rays towards the principal axis whereas a concave lens diverges the light rays away from the principal axis.

For a Concave lensThere are only 2 casesThey areObject is Placed at InfinityObject is Placed between Infinity and Optical CenterCase 1 - Object is Placed at infinityIn this Case Object is kept far away from mirror almost at infinite distanceSo we draw rays parallel to principal axisSince ray pa. A convex lens in which light rays that enter it parallel to its axis converge at a.
