1. Distance from the light source: The distance between the light source and the object being illuminated affects the intensity of the light received. To control this variable, the distance between the light source and the objects being compared should be kept constant.
2. Angle of incidence: The angle at which light strikes an object affects the intensity of the light received. To control this variable, the angle at which the light strikes the object should be kept constant. This can be achieved by placing the object being compared at the same angle to the light source.
