NOTES:1. You can place the diamond exhibits anywhere in either room (although they cannot be grouped together so try to space them out as much as possible).2. You can place the start and end of laser beam on a wall anywhere in either room.3. You can use as many mirrors as you need; however, if you use more than 9, you will lose 1 mark for each additional mirror, and if you successfully use less than 9, you will gain 1 bonus mark.4. A mirror can be used to bounce the laser beam multiple times.5. Laser beams can cross each other.1. Using a pencil, LIGHTLY trace where you think the path of the laser beam will travel.You may need to try out a few ideas before you are sure. Hint: start with the hardest2.ray (in the middle?) and go from there.Cut and paste your mirrors where you need them. To change the angle of the rays, put your mirrors on a slant.3. Draw the Normal to the surface of the mirror. Use your protractor to make sure thatthe angle of incidence = angle of reflection.4. Draw your final rays permanently with a coloured pencil or marker. Draw arrows to show the direction of the laser.5. Glue your ray gun and sensor on your map.6. Cut and paste your diamond exhibits where you want them on the map. Be careful not to leave any gaps where a burglar can get at the diamonds.7. Give your security system a name.
