WebConstruct ray diagrams to determine the location, orientation, size, and type of images formed by a curved mirror. Using the protractor and the ruler, copy each of the diagrams (A – F) below on a separate sheet of paper. As much as possible, use the four principal rays to locate the image formed in a curved mir. WebEven if the lens' curvature is not circular, it can focus the light rays to a point. It's just an assumption, for the sake of simplicity.

If the object is further away from the mirror than the focal point, the image will be upside-down and real---meaning that the image appears on the same side of the mirror as the object. The closer the object comes to the focal point (without passing it), the bigger the image will be.
