A convex mirror in a store has a radius of curvature of 0.55 m. If a customer is 10 m from the mirror, where is the customer's image in the mirror? What is the magnification of the image of the image? What is the orientation of the image?

A concave mirror has a focal length of 40 cm. Determine the object position for which the resulting image is upright and 4 times the size of the object.

You want to form an image on a screen 10 m from a mirror. If the image is 7 times bigger than the object, what type of mirror do you need? What is the radius of curvature?

An object is 20 cm in front of a lens of focal length 9.5 cm. A second lens of focal length -30 cm is 15 cm behind the first lens. Find the location of the final image and its magnification.
