Ball and image pass when qp=. When this istrue,121ppp=morp1100=m.As the ball passes the focal point, the image switches from infinitely far above the mirror toinfinitely far below the mirror. As the ball approaches the mirror from above, the virtualimage approaches the mirror from below, reaching it together when
