A concave mirror and a plane mirror (f = 8.30 cm) are facing each other and are separated by a distance of 23.0 cm. An object is placed among the mirrors and is 11.5 cm from each mirror. Consider the light from the object that reflects first from the plane mirror and then from the concave mirror. Discover the location of the image that this light produces in the concave mirror. Specify this distance relative to the concave mirror.
