Formation of Image by a Convex Lens
Formation of Image by a Convex Lens - When an object is placed in front of a lens, light rays coming from the object fall on the lens and get refracted. The refracted rays produce an image at a point where they intersect or appear to intersect each other. The formation of images..

The previous chapter dealt with the refraction of light by lenses and also about the formation of various types of images by a lens for different positions of the object. In this chapter let us find out how lenses are used in optical instruments like microscopes and telesc..

Tutors are AMAZING, and They helped me understand every single part of the problem and because of the way they explained everything, i had no questions to ask. It was a learning experience to remember. :)
This tutors rocked out loud. They were THE BEST tutors. They teaches you everything and explains how to do it and why to do it,awesome tutoring!!!-Ariana
Great sessions, learned a lot and got lots in and techniqul problem systm is showing me out of the session when i am not ,This is Awesome - Haley
Very informational yet simple and easy to comprehend. Tutor Vista is helping me a lot.
