refraction, total internal reflection and polarization, will be examined. Experiment 1: The Law of Reflection Figure 8.1: Optics table setup for the law of reflection experiment. Introduction: The shape and location of the image created by reflection from a mirror of any shape is determined by just a few simple principles.
The Law of Reflection
The Law of Reflection. The angle of reflection equals the angle of incidence. When we see ourselves in a mirror, it appears that our image is actually behind the mirror. This is illustrated in Figure 6. We see the light coming from a direction determined by the law of reflection. The angles are such that our image is exactly the same distance ...
25.2 The Law of Reflection
The law of reflection states that the angle of reflection equals the angle of incidence— θr = θi. The angles are measured relative to the perpendicular to the surface at the point where the ray strikes the surface. Figure 2. Light is diffused when it reflects from a rough surface. Here many parallel rays are incident, but they are reflected ...
Physics Tutorial: The Law of Reflection
The Law of Reflection. Light is known to behave in a very predictable manner. If a ray of light could be observed approaching and reflecting off of a flat mirror, then the behavior of the light as it reflects would follow a predictable law known as the law of reflection. The diagram below illustrates the law of reflection.
Investigating Reflection
Apparatus to investigate reflection. Set up the apparatus as shown in the diagram. In the middle of the paper use a ruler to mark a straight line of about 10 cm long. Use a protractor to draw a 90° line that bisects (cuts in half) the 10 cm line. Place the mirror on the first line as shown in the diagram above.

1.2 The Law of Reflection
Figure 1.7 (a) When a sheet of paper is illuminated with many parallel incident rays, it can be seen at many different angles, because its surface is rough and diffuses the light. (b) A mirror illuminated by many parallel rays reflects them in only one direction, because its surface is very smooth. Only the observer at a particular angle sees the reflected light.

Be sure that the pins are perpendicular to the paper. 3) Move your head so that your line of sight is in the same direction as the eye shown above. Your eyes should be about 1 cm above the paper. 4) Look for the reflections (virtual images) of pins A and B in the mirror. Move your head until the two reflections line up.
16.1 Reflection
The law of reflection states: The angle of reflection, θ r θ r, equals the angle of incidence, θ i θ i. This law governs the behavior of all waves when they interact with a smooth surface, and therefore describe the behavior of light waves as well. The reflection of light is simplified when light is treated as a ray.
Reflection and Fermat's Principle
Fermat's Principle:Reflection. Fermat's Principle: Light follows the path of least time. Of course the straight line from A to B is the shortest time, but suppose it has a single reflection. The law of reflection can be derived from this principle as follows: Since the speed is constant, the minimum time path is simply the minimum distance path.
Experiment: Investigating the Law of Reflection: a ...
A fundamental law of light is that the angle of incidence equals the angle of reflection when light strikes a reflecting medium. The angles are commonly measured normal (perpendicular) to the reflecting surface. This law can be studied quantitatively by students using only seven littleBits, three mounting ;boards, a small mirror, and commonly available materials. </p>

Describe an experiment to verify the laws of reflection of light.
Remove the pins and draw small circles around the pinpricks. Remove the mirror also. Join P'Q' and produce the straight line to meet at B. Measure ∠ A B N = i and ∠ C B N = r. It is found that ∠ i = ∠ r. This proves that the Angle of Incidence is equal to the Angle of Reflection. As the incident ray, the reflected ray and the normal lie ...
Laws of Reflection
Definition: The law of reflection defines that upon reflection from a smooth surface, the angle of the reflected ray is equal to the angle of the incident ray, with respect to the normal to the surface that is to a line perpendicular to the surface at the point of contact. The reflected ray is always in the plane defined by the incident ray and ...
