A concave makeup mirror is designed so that a person 26 cm in front of it sees an upright image magnified by a factor of two. What is the radius of curvature of the mirror?

R=_ in m

Solutions

Expert Solution

First of all we need to consider the case where a concave mirror forms a magnified and upright image for an object which is clearly when the object is placed between the focus and the mirror. Now the formula for magnification is :

By inserting the values in meters

Now we can find the focal length using these values of image and object distances:
