- A plane mirror and a concave mirror (f = 7.50 cm) are facing each other and are separated by a distance of 17.0 cm. An object is placed between the mirrors and is 8.50 cm from each mirror. Consider the light from the object that reflects first from the plane mirror and then from the concave mirror. Find the location of the image that this light produces in the concave mirror. Specify this distance relative to the concave mirror. Number i Object (-²) Units ◄►A light beam is traveling through an unknown substance.
