Week 13 SGM 1) A ray of light is incident on the surface of a flat mirror as shown in the pictures below. For each, identify the angles of incidence and reflection and draw the reflected ray. Mirror a. b. C. Mirror Oincident a Oincident b= O incident c= Oreflect a = Oreflect b = Oreflect= Mirror Mirror d. O incident d= Oreflect d = 2) A number of parallel rays are incident on the curved reflective surface shown below. Determine how each ray will reflect when it hits the mirrored surface. Scientific Abilities Is able to represent the path light travels using rays Missing No attempt is made to represent the path light follows Inadequate The rays are drawn to represent light do not follow the correct paths Needs Improvement The rays drawn show the correct path but important information such as relevant angles or distances have been left out Adequate The rays drawn show the path light travels correctly and all relevant information has been included Use these reflected rays to explain what you might see if you look at this surface Scientific Abilities Is able to make a reasonable prediction based on a hypothesis Missing No prediction is made. The experiment is not treated as a testing experiment. Inadequate A prediction is made but it is identical to the hypothesis, OR Prediction is made based on a source unrelated to hypothesis being tested, or is completely inconsistent with hypothesis being tested, OR Prediction is unrelated to the context of the designed experiment. Needs Improvement Prediction follows from hypothesis but is flawed because relevant experimental assumptions are not considered and/or the prediction is incomplete or somewhat inconsistent with hypothesis and/or prediction is somewhat inconsistent with the experiment. Adequate A prediction is made that follows from hypothesis, is distinct from the hypothesis, accurately describes the expected outcome of the designed experiment, incorporates relevant assumptions if needed.
