The angles are measured relative to the perpendicular to the surface at the point where the ray strikes the surface. Law of Reflection: The law of reflection states that the angle of reflection equals the angle of incidence: θr = θi. The image appears to come from the direction the rays are coming from when they enter the viewer’s eyes. The two rays shown are those that strike the mirror at just the correct angles to be reflected into the eyes of the viewer. Mirror Reflection: An image in a mirror appears as though it is behind the mirror. The angles are such that our image appears exactly the same distance behind the mirror as we stand away from the mirror. When we see our reflection in a mirror, it appears that our image is actually behind the mirror - we see the light coming from a direction determined by the law of reflection. The law of reflection is very simple: The angle of reflection equals the angle of incidence. The law of reflection is illustrated in, which also shows how the angles are measured relative to the perpendicular to the surface at the point where the light ray strikes. In fact, the only way we can see an object that does not itself emit light is if that object reflects light. Large telescopes use reflections to form images of stars and other astronomical objects. When you look at the text in a book, you are actually seeing the light that is reflected from it. Whenever you look into a mirror or squint at sunlight glinting off a lake, you are seeing a reflection. Formulate the relationship between the angle of reflection and the angle of incidence.
