Investigating Reflection using ray boxes
Two year 7 pupils decided to investigate whether there was a link between a ray of light
that hits a mirror and its reflected ray. Using a ray box and slit, the pupils shone a ray
of light along 6 previously drawn incident rays. In each case the reflected ray was
marked and drawn in.

1. /Using a protractor complete the table and plot points to show the results on the
grid below.
2. One of their results is obviously wrong, ignore this and draw a correct line for that
particular ray.
3. What conclusions can you draw from
their results?
