Which rules apply to concave mirror ray tracing? Click all that apply. a If an incident ray travels parallel to the principal axis on the way to the curved mirror, the ray will be reflected in away from the focal point behind the mirror. b If an incident ray travels parallel to the principal axis on the way to the curved mirror, the ray will be reflected back through the focal point. c If an incident ray travels toward the focal point on the way to the curved mirror, the ray will be reflected back parallel to the principal axis. d If an incident ray travels through the focal point on the way to the curved mirror, the ray will be reflected back parallel to the principal axis
