Increasing in magnitude and negtive .
Exp- if we put an object at infinity then image form at focus and if we put an object beyond radius of curvature then image form between focus and radius of curvature so distance is increasing but due to sign convention it is negative....

A concave mirror (f = 39 cm) produces an image whose distance from the mirror is one-fifth the object distance. (a) Determine the object distance. cm (b) Determine the (positive) image distance. cm A concave makeup mirror is designed so the virtual image it produces is twice the size of the object when the distance between the object and the mirror is 30 cm. What is the radius of curvature of the mirror? R =

2. Calculate the image distance from the equation-+-=- PS: for a concave mirror, the focal length is taken to be positive (); for a convex mirror, the focal length is taken to be negative ). The object distance do is taken to be positive in either case. The sign convention is as Tollows: If di is positive, the image is real, and if di is negative, the image is virtual. 3. How might you determine the focal...

2. (3 pts.) A spherical, concave mirror has a radius of curvature of 75.0 cm. You have a small, well-lit plastic action figure that is 10.0 cm tall, and you want to create a real image of it that is 1.50 times as large as the original object. (Hint: Watch your signs the real image will be inverted, so the magnification should be negative.) At what distance from the mirror should you place the object? Show your work completely
