Introduction

I.S.P. Science Department General Physics Laboratory Report #10 "The Law of Reflection" Laura Canzano Block: B Mr. Gonzalez Due Date: May 24, 2002 Experiment # 10 "The Law of Reflection" Students: Roberto Aleman, Javier Robayna, Shadia Palis, Laura Canzano, Giovanna, and Juan Ramon de Leon. Date Performed: May 16, 2002 Introduction: The purpose of this experiment is to understand the law of reflection using the simplest way to see the phenomenon. The problem or the research question being addressed in this experiment is whether or not we will be able to see clearly the reflected ray, and if the law will be correct. Reflection is described by the Encarta Encyclopedia as the "phenomenon of wave motion, in which a wave is returned after impinging on a surface." The laws of reflection state that the angle of incidence is equal to the angle of reflection and that the incident ray, the reflected ray, and the normal to the surface at the point of incidence all lie in the same plane. ...read more.

Middle

On the component holder place the ray optics mirror (the flat surface facing the light source), and turn the holder in such a way that the beam of light is lined with the mark that says 0�. Then turn the holder to place the ray on the 10� mark and record the reflected ray. Repeat this for every 10� until you reach the mark that says 90�. Data Collection: Angle of: Incidence Reflection 1 Reflection 2 0� 0.00� 0.00� 10� 10.1� 10.0� 20� 20.0� 20.0� 30� 30.0� 30.0� 40� 40.0� 40.0� 50� 50.1� 50.0� 60� 60.0� 60.0� 70� 70.1� 70.1� 80� 80� 80.1� 90� 89.9� 89.9� Discussion and Evaluation: While performing this experiment with my classmates we realized that the results were most of the time the same for both trials. The differences that we found could be attributed to the fact that the closer the light beam was to the 90� mark the less visible it became. ...read more.

Conclusion

The relationship that was observed between the angle of reflection and the angle of incidence is that they are equal and they lay in the same plain, therefore they do follow the laws of reflection. The procedure of this experiment was adequately stated and we were able to follow it very easily. All the equipment were used appropriately, and this procedure was very good for the purpose of this experiment. Conclusion: Our findings from this experiment is that we were able to observe the phenomenon of reflection using a very simple technique. I hypothesized that we would be able to observe the laws of reflection by shooting light at a smooth surface mirror, and find out that the angle of incidence would equal the angle of the reflection in respect to the normal. My hypothesis, therefore, was proven correct for our result show exactly what was attempted in this experiment to be true. What was proven in this experiment is that it is possible to observe the laws reflection without using extremely high technological equipment. ...read more.

Pg5 Who is most at risk? People that are most at risk using sun beds are those with fair or tender skin, people with skin type 1, as they have a higher risk of suffering from problems. In 2003 International Co-operation on Non-Ionizing Radiation Protection, ICNIRP, published recommends against the use of UV-emitting appliances for tanning or other non-medical purposes.

After such a course you may rest the skin for a while. Approximately one month after a course your skin will have lost much of the tan. On the other hand you may prefer to have one or two sessions per week after a course has elapsed in order to keep a tan.

Sunlight spread into its different colours by a prism creates a continuous spectrum. From violet to red, the spectrum blends smoothly from one colour to the next. Many other sources of light do not produce a continuous spectrum. For example, a street lamp may produce bright yellow, blue, and a
