To find the focal length of a convex mirror using a convex lens.
Convex Mirror – Focal Length: The Theory: Convex mirror A convex mirror is a curved mirror in which the reflecting surface bulges towards the light source. Convex mirrors reflect light outwards; therefore they are not used to focus light. A convex mirror is also known as fish eye mirror or diverging mirror. The image formed … Continue reading “To find the focal length of a convex mirror using a convex lens.”
