Parallel rays of light incident on a convex lens are refracted and converge to a point on the principal axis. This point is known as the principal focus of the lens.
When parallel rays of light pass through a convex lens, they converge at a point on the opposite side of the lens from where they originated. This convergence is due to the lens’s ability to refract light, bending the rays towards its optical axis. The point at which the rays meet is called the principal focus. Convex lenses are converging lenses, and the phenomenon is used in various optical applications like cameras and magnifying glasses. The focal point represents the point of maximum convergence, providing a focused image for parallel incident light rays.
