30 < of incidence Draw a straight line where you want your mirror to be on the page Measure 30 degrees with the protractor and draw a line. Label it your angle of incidence M I RROR

30 < of incidence Shine the laser down the angle of incidence line into the mirror Trace over the reflected line that the laser creates Measure the angle of reflection and record the number in your table 13L M I RROR < of reflection
