🔬 Part 1: Understanding Reflection

1. What is reflection?

Light passing through a surface

Light bouncing off a surface

Light being absorbed by a surface

Light changing colors

2. According to the law of reflection, the angle of incidence ____________ the angle of reflection.

is greater than

is less than

equals

has no relationship to

3. Which surfaces reflect light well? (Check all that apply)

Mirrors

Aluminum foil

Black construction paper

Calm water surface

4. In your own words, explain what happens when light reflects off a flat mirror:

📐 Part 2: Measuring Angles

5. Look at the diagram below. A light ray hits a mirror at a 30° angle of incidence. What will the angle of reflection be?

Angle of reflection: ______°

6. Draw your own reflection diagram. Show a light ray hitting a mirror at a 45° angle of incidence. Include and label:

• The incoming light ray

• The mirror surface

• The reflected light ray

• Both angles with their measurements

7. During your investigation, you measured these angles. Complete the table:

Trial 1: Angle of incidence = 20°, Angle of reflection = ______°

Trial 2: Angle of incidence = 60°, Angle of reflection = ______°

Trial 3: Angle of incidence = ______°, Angle of reflection = 35°

🏠 Part 3: Real-World Applications

8. List three objects in your daily life that use reflection:

1. _________________________________

2. _________________________________

3. _________________________________

9. Explain why car side mirrors are useful for drivers. How do they use the properties of reflection?

10. Compare reflection on a mirror versus reflection on white paper. What differences did you observe in your investigation?
