Reflection of Light Quiz

What is the purpose of the practical?

• To determine the relationship between the angle of incidence and the angle of reflection

• To measure the angles between the normal and the incident ray

• To draw a line graph showing the results

• To shine a ray of light at a mirror

What should be included in the table of results?

• The angle of incidence and the angle of reflection

• The angle of reflection and the angle between the reflected ray and the normal

• The angle of incidence and the angle between the normal and the incident ray

• The angle between the reflected ray and the normal and the angle of reflection

If you were to plot your results and the law of reflection is true, then the angle of incidence should equal the angle of reflection and you get a straight line graph.

What should be drawn on the line graph?

• Axes with the angle of incidence on the x-axis and the angle of reflection on the y-axis

• Axes with the angle of reflection on the x-axis and the angle of incidence on the y-axis

• Axes with the angle of incidence on both the x-axis and y-axis

• Axes with the angle of reflection on both the x-axis and y-axis

What conclusion can be drawn from the experiment?

• The angle of reflection is greater than the angle of incidence

• The angle of reflection is equal to the angle of incidence

• The angle of reflection is less than the angle of incidence

• The angle of reflection cannot be determined

What should be included in the diagram of light reflection?

• Incident ray, normal line, reflected ray, angle of incidence, angle of reflection

• Incident ray, reflected ray, angle of incidence, angle of reflection

• Incident ray, normal line, reflected ray

• Incident ray, reflected ray, angle of incidence

James did this experiment for the following angles of incidence: 30 degrees, 40 degrees, 50 degrees, 60 degrees. Which angle of reflection was not measured accurately in James' experiment?

• 30°

• 40°

• 50°

• 65°

How can you tell that the angle of reflection was not measured accurately?

• It does not fit the pattern of the other results

• It is equal to the angle of incidence

• It is greater than the angle of incidence

• It is less than the angle of incidence

What word is used to describe a result that doesn't fit the pattern?

• Anomalous

• Accurate

• Consistent

• Precise

What is the most common reason for the inaccuracy in measurements for this experiment?

• Lack of precision in reading the angles

• The mirror was not placed correctly

• The ray box was not aligned properly

• The table was not level

What should be done with the anomalous result?

• Exclude it from the analysis

• Average it with the other results

• Repeat the measurement

• Ignore it completely
