The correct Answer is:
To solve the question "Which lens has one surface plane and another surface convex?", we can follow these steps: ### Step 1: Understand the Types of Lenses Lenses are classified based on the curvature of their surfaces. The main types are: - **Convex Lens**: Both surfaces are convex. - **Concave Lens**: Both surfaces are concave. - **Plano-Convex Lens**: One surface is flat (plane) and the other is convex. - **Plano-Concave Lens**: One surface is flat (plane) and the other is concave. ### Step 2: Analyze the Options Given the options: 1. Biconcave 2. Biconvex 3. Plano-convex 4. Plano-concave We need to identify which of these options has one flat surface and one convex surface. ### Step 3: Identify the Correct Lens - **Biconcave**: Both surfaces are concave. - **Biconvex**: Both surfaces are convex. - **Plano-Convex**: One surface is flat (plane) and the other is convex. This matches our requirement. - **Plano-Concave**: One surface is flat (plane) and the other is concave. ### Step 4: Conclusion The lens that has one surface plane and another surface convex is the **Plano-Convex Lens**. ### Final Answer **The correct answer is: Plano-Convex Lens.** ---
