Data and Observations
1. Record your observations in the data tables.
Type your answer here:

Table 1. Angles of Incidence and Angles of Reflection for a Beam of Light Reflected off a Mirror
Angle of incidence (°) Angle of reflection (°)






Table 2. Angles of Incidence and Angles of Refraction for a Beam of Light Refracted through a Glass Lens
Angle of incidence (°) Angle of refraction (°)





Conclusions
1. Draw a diagram (develop a model) that shows what happens to light when it reflects off a mirror. Look for patterns in your data to help you develop your model. Hint: Is the angle of reflection always greater than, less than, or equal to the angle of incidence? Include labels.

2. Use your model to predict the angle of reflection of a beam of light reflected off a mirror if the angle of incidence of the beam of light is 40 degrees.

3. Draw a diagram (develop a model) that shows what happens to light when it is refracted through a glass lens. Look for patterns in your data to help you develop your model. Hint: Is the angle of refraction always greater than, less than, or equal to the angle of incidence? Include labels.
