Answer:Hypothesis: The angle of incidence affects the angle of reflectionIndependent variable: The angle of incidenceDependent variable: The angle of reflectionControl variables:Surface type: The surface that the light is reflecting off of should be smooth and flat to ensure that the angle of incidence is the only variable affecting the angle of reflection.Light source: The light source should be consistent and unchanging to ensure that the angle of incidence is the only variable affecting the angle of reflection.Distance: The distance between the light source and the surface should be held constant to ensure that the angle of incidence is the only variable affecting the angle of reflection.
