Students of Presidium participated in the Science Subject Activity-Image Formation by Convex Lens. A convex lens is a converging lens. When parallel rays of light pass through a convex lens, the refracted rays converge at one point called the principal focus. The distance between the principal focus and the center of the lens is called the focal length. In the case of a convex lens, if we bring the object close to the lens, the image's size keeps on increasing. As you bring the object closer to the lens, we get the image enlarged. Students learned how to get different types of images and how they are useful for us to implement in our daily lives. They represented various images by placing the object at different positions such as infinity, focus, etc. and learned various images formed after refraction.
