ISA "the angle of incidence equals the angle of reflection" section 2

Hypothesis Q- Is the hypothesis correct? (Can you tell from the graph?) What is the pattern of results? Quote data from the results. At least two points of data. Any anomalies? How do you know if there aren't any? Variables Q- CV, IV, DV Control variable has lots - mirror, angle of mirror, distance of ray box from mirror, voltage of ray box etc. What are the limitations of the experiment? -Thickness of light (you have to guess the middle of the ray of light)-Mirror wobbles about-The paper  moves easily

Case study QsSketching a graph:-you only need to label axis and add a line of best fit -It is a sketch! Look at the case study's results carefully. Not all of them will back up your hypothesis just about 2 of them. Quote data of both if they back up your results. If they are different to yours, why? Have the persons results (in the case study) got anomalies that have wrongly been counted into the mean? Context Q- It is on your pink sheet It should be related to something else. In this case it is related to car designs and the mirrors on/in them. The angle of reflection allows driver to see cars behind it.
