1. What happens to an incident ray that passes through the focal point of a concave mirror? An incident ray passing through the focal point is reflected so that it is parallel to the axis. An incident ray that can be extended to pass through the focal point of a convex mirror will be reflected parallel to the axis. 21-Feb-16
