Year 6 have been investigating the law of reflection this week. When rays of light reflect, they obey the law of reflection: the angle of incidence always equals the angle of reflection. Children held a mirror on a piece of paper and made a very narrow slit in a piece of card. They dimmed the lights and shone a torch through the slit towards the mirror. On the white paper, they had to look for the incident ray and the reflected ray of light. They had to play around with the angle of the torch and the distance they held it from the mirror. Using a pencil and ruler they drew the incident and reflected rays on the paper. Then, they drew a dashed line perpendicular to the mirror, from the point where the incident and reflected rays met. This is the normal line. We were impressed with the children’s curiosity and teamwork!
