1Recalling the equipment required for investigating the law of reflection with a ray box
2The first step to investigating the law of reflection with a ray box is to draw out a template showing the position of the mirror and incident ray with respect to the normal.
3When lining a mirror up with the mirror line on a paper diagram, you need to line the back of the mirror up with the mirror line
4You need to line the incident ray up with the ray on paper so that the drawn line is exactly in the middle of the light ray.
5To accurately mark the reflected ray, you need to mark small crosses with a sharp pencil in the middle of the reflected ray.
6To measure the angle of the reflected ray, you must use a protractor to measure the angle between the reflected ray and the normal.
