Webb21 dec. 2024 · The ability of a lens to bend light is really what gives it its power in Ray Optics. The greater a lens’s strength, the greater its ability to refract light passing through it. Power defines the converging ability of a convex lens and the diverging ability of a concave lens. The number of light bends increases as the focal length reduces. WebbIf the lens is biconcave or plano-concave, a collimated beam of light passing through the lens is diverged (spread); the lens is thus called a negative or diverging lens. The beam, …
