Maelezo
Concave Mirror: A concave mirror can focus light rays, allowing for a magnified image of the face. This magnification helps in seeing details more clearly, which is particularly useful for shaving.
Convex Mirror: A convex mirror creates a smaller, wider image, which is not suitable for precise tasks like shaving.
Plane Mirror: A plane mirror shows a true reflection but does not magnify, making it less effective for grooming.
Parabolic Mirror: Parabolic mirrors are used for specific applications, like telescopes, but not for shaving.
