This lesson, Year 6
learned more about how light travels, and how we can use mirrors to see. Our
experiments proved that the angle light arrives at on a reflective surface,
such as a mirror (known as the angle of incidence), is the same angle that it
reflects off at (the angle of reflection).
We also made our own
periscopes, making sure that our two mirrors were angled at 45°. The combined
45° angles of incidence and reflection meant that light travelling onto our top
mirror travelled exactly onto the bottom mirror, and straight out into our
eyes, allowing us to see.
If this sounds
complicated, ask a Year 6 student and they can explain it all to you!
