To solve the problem step by step, we will use the concepts of spherical mirrors, magnification, and the mirror formula. ### Step 1: Understand the given information - The size of the image is twice the size of the object. - The distance of the object (the person's face) from the mirror is 20 cm. ### Step 2: Identify the type of mirror Since the image is larger than the object, we can conclude that the mirror is a concave mirror. ...
