Answers for quiz questions 1. (a) A student shines a light from a ray box onto a mirror. The image below shows the path of the ray as it leaves the ray box and hits the mirror. Draw on the reflected ray, and label the angle of incidence and angle of reflection. [4 marks] Line reflected off the mirror with arrow head in correct direction Angle of reflection same as angle of incidence (judged by eye) Angle of incidence correctly labelled to the left of the normal Angle of reflection correctly labelled to the right of the normal (b) [2 marks] Any two correct uses of mirrors. Examples may include: Periscopes To see your reflection To see behind you in the car 2. (a) If the quality of the image is important, then right angled triangular glass blocks can be used instead of mirrors. Complete the diagram to show the position and orientation of the glass blocks. [1 mark] (b) On the above image, use two ray lines to show that the image seen is upright [2 marks]
