Question
Which type of mirror is utilized in solar furnaces to
focus sunlight and generate heat?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.
