A concave mirror of focal length 15 cm is at x=0. An object is placed at x=20 cm. A convex mirror of focal length 15 cm is at x=50 cm. Consider that light rays from the object strike the concave mirror first. Using the image formed by the concave mirror as the object, determine the location and magnification of the final image (formed by the convex mirror).

An object is 38 cm away from a concave mirror that has a focal length of 12 cm. a. Find where the image of the object will be located by solving for the image position, d , in the mirror equation. i b. Will the image be upright or inverted? Use the magnification equation and the fact that if magnification (m) is negative then the image is inverted.

Answer True or False for all statements. A convex mirror never forms a real image of a real object. The virtual image formed by a convex mirror is always enlarged. A concave mirror always forms a virtual image of a real object. A virtual image formed by a concave mirror is always enlarged. A concave mirror always forms an enlarged real image of a real object. When an object is placed between a concave mirror and its focal point, the...
