shows a ray of light reflected from mirror 1 at point P and striking mirror 2 at point Q. 45° P Q plane mirror 1 plane mirror 2 ray of light On , • clearly mark the position of the normal at Q, • draw the ray reflected from point Q, • mark the angle of reflection at Q using the letter r, State the law you used to draw the reflected ray. Compare the direction of the ray reflected from mirror 2 at Q with the direction of the ray incident on mirror 1 at P. Tick one box. The ray of light reflected from mirror 2 is parallel to the incident ray at P, perpendicular to the incident ray at P, at an angle of 45° to the incident ray at P. A thin, converging lens forms an image, I, of an object, O, as shown in . O 24 cm 10 cm 8 cm I On , label a principal focus of the lens, using the letter F. State the focal length of the lens. focal length = cm
