- 8. Multiple ChoiceWhere is the angle of reflection located?Between the mirror and the incident rayBetween the mirror and the reflected rayBetween the normal line and incident rayBetween the normal line and reflected ray
- 9. Multiple ChoiceAn incident light ray strikes a flat mirror at an angle of 30° from the normal. The reflected light ray reflects off the mirrorat an angle of 30° from the mirror edgeat an angle of 60° from the normalat an angle of 30° from the normalat an angle of 90° from the mirror edge
- 10. Multiple ChoiceAs an object moves towards a flat mirror, its imagemoves closer to the mirrormoves further from the mirrorflips upside down
- 11. Multiple ChoiceWhich of the following letters will look the same in the mirror?ABCD
- 12. Multiple ChoiceIf the angle of incidence is 60 degrees from the normal line, what is the angle of reflection and the total angle between the incident and reflected ray?Angle of reflection = 30
Total angle = 90Angle of reflection = 60
Total angle = 90Angle of reflection = 30
Total angle = 120Angle of reflection = 60
