    focus sunlight and generate heat?
    A Convex Correct Answer Incorrect Answer
    B Concave Correct Answer Incorrect Answer
    C Both convex and concave Correct Answer Incorrect Answer
    D Plane Correct Answer Incorrect Answer

    Solution

    Concave mirrors have a reflective surface that curves inward, resembling a portion of the inner surface of a sphere. This design allows them to converge light rays to a single focal point. Due to this property, concave mirrors are extensively used in applications requiring light concentration, such as solar furnaces, where they focus sunlight to produce intense heat. These mirrors are also prevalent in everyday devices like torches, vehicle headlights, and shaving mirrors.
