Science lab lesson

In our first visit to the science lab in term 3, we learnt about light a were instructed to do a very simple experiment on light. The experiment was actually more simple than it seemed. It was simply a test to find out the true nature of reflection and also to clear the more simple doubts we had in our mind about reflection. All we were required to do was to shine a ray of light from the light box which we were provided in a certain angle and then measure the reflected angle. Then suddenly, disaster struck! For reasons totally unknown to me and my partner, half of the reflected ray of light was "missing"! Try as we might, we were still unable to solve our problem. Finally, we consulted Ms Nada as the problem was easily solved. After this experiment all the misconceptions in my mind about reflection was cleared.
