SECTION A
Answer ALL questions.
For questions 1–10, in Section A, select one answer from A to D and put a cross in the box . If you
change your mind, put a line through the box and then mark your new answer with a cross .
1 A ray of light in air is incident on a glass surface. The angle of incidence is less than the
critical angle.
Which of the following describes what happens to the ray of light?
A partially reflected and partially transmitted
B refracted away from the normal
C totally internally reflected
D transmitted along the normal
(Total for Question 1 = 1 mark)
2 There is an increase in the intensity of light incident on a light dependent resistor
(LDR). This causes a change in the number of conduction electrons and a change in the
resistance of the LDR.
Which row of the table describes these changes?
A
B
C
D
(Total for Question 2 = 1 mark)
Number of conduction electrons Resistance of LDR
decreases decreases
decreases increases
increases decreases
increases increases
