What type of mirror is used by dentists to get an enlarged image of teeth?
A. Plane mirror
B. Concave mirror✓ Correct Answer
C. Convex mirror
D. Cylindrical mirror
💡 Solution & Explanation
Dentists use a concave mirror because it forms magnified and virtual images when an object is positioned within its focal length, enabling detailed examination of teeth. Plane mirrors produce life-sized images without magnification, while convex mirrors form diminished images and provide a wider field of view rather than close-up enlargement. Concave mirrors are also widely utilized in shaving mirrors and astronomical telescopes.
