**LAW OF REFLECTION**

 * 1) On a sheet of A4 paper, draw a mirror and a normal line.
 * 2) Place a mirror accurately on the mirror line.
 * 3) Shine three incident rays at the normal with large, medium and small angles of incidence.
 * 4) Plot the three reflected rays using two dots.
 * 5) Draw in the incident and reflected rays.
 * 6) Measure the angles of incidence and reflection and write them in a table.
 * 7) What is the simple relationship between the angles?

For good results, this investigation needs you to be very accurate.
 * FORMATION OF A VIRTUAL IMAGE**
 * 1) On a sheet, draw a mirror, object (O) and four incident rays as shown.
 * 2) Shine light along each incident ray (you may have to move the mirror each time).
 * 3) Plot the reflected rays.
 * 4) Draw virtual rays by extending the reflected rays back behind the mirror.
 * 5) What do you notice about the virtual rays?
