  • 1. The diagram shows a single ray of light being directed at a plane mirror. What is the angle of incidence and angle of reflection?
A) Angle of incidence = 40o, angle of reflection = 40o
B) Angle of incidence = 40o, angle of reflection = 50o
C) Angle of incidence = 50o, angle of reflection = 50o
D) Angle of incidence = 50o, angle of reflection = 40o
  • 2. Which one of the following is WRONG about the laws of reflection?
A) The laws of reflection can be applied to the plane mirror only.
B) The incident ray and the reflected ray lie on the same plane.
C) The angle of incidence is equal to the angle of reflection.
D) The incident ray and the normal lie on the same plane.

B) A
C) D
D) B
  • 4. Which one of the following is not the characteristics of the image formed by a plane mirror?
A) Laterally inverted
B) Has the same size as the object

D) Real
  • 5. A man 1.8 m tall wishes to see his full length in a plane mirror. The minimum length of mirror that he must buy is
A) 1.8 m
B) 0.9 m
C) 1.5 m
D) 1 m
  • 6. A boy is running at a speed of 5 m/s towards a plane mirror. The boy and his image in the mirror are moving

D) towards from each other at a speed of 5 m/s
  • 7. A piece of tin foil is crumpled by a boy. Why is the surface of the crumpled foil not as shiny as before?
A) This is because light is not reflected but absorbed by the tin foil.
B) This is because light is reflected in different directions after striking the surface.
C) This is because light is reflected in the same direction after striking the surface.
D) This is because specular reflection occurs.
  • 8. A boy sits in an optician’s chair, looking into a plane mirror, which is 2m away from him, and views the image of a chart which faces the mirror and is 50 cm behind his head. How far away from his eyes does the chart appear to be?
