2. An incident ray hits a reflecting surface with an angle of 30° with the normal and reflected back. What will be the measure of the reflected angle?

• 30°
• 60°
• 90°
• 45°

3. The dotted line (C) is called the

• reflected ray
• incident ray
• normal
• incident angle

4. The rays A and B are defined as:

• A: reflected ray, B: incident ray
• A: incident ray, B: reflected ray
• A: normal, B: reflecting surface
• A: incident ray, B: normal

5. If the angle between rays A and B (i+r) is equal to 40°, what is true about angles i and r:

• i = 40°, r = 40°
• i = 30°, r = 10°
• i = 15°, r = 25°
• i = 20°, r = 20°
