Instructions
1. Write the required information on the title page of the Student Booklet.
2. This examination consists of two parts. Part A: 10 multiple-choice questions and
Part B: 15 constructed-response questions.
3. Answer all questions in the Student Booklet, showing all your work and units.
4. You are permitted to use writing instruments and a calculator with or without
graphic display designed mainly to perform mathematical calculations.
Before the exam starts, data and programs stored in the calculator’s memory
must be deleted.
Using a calculator containing stored data or programs will be considered as
cheating.
You may not share your calculator with other students. Communication in any form
between calculators is forbidden.
Other electronic devices that have a calculator function are strictly forbidden.
5. You may refer to the information provided in the Appendix of the Question
Booklet. The use of any other reference material is strictly forbidden.
6. Hand in the Question Booklet and the Student Booklet at the end of the
examination.
NOTE: Each question is worth four marks.
Figures are not necessarily drawn to scale, unless stated.
Significant figures will not be evaluated.
Time: 3 hours

3. Anton and Frank are given two unidentified transparent materials labelled Material W and
Material Z. They determine experimentally how light passes through them and record their
results in the diagrams below.
They are given two other materials, labelled Material X and Material Y. They are given the
speed at which light travels through them. The speed at which light travels through
Material X is v  3.00  108
m/s and through Material Y is v  2.50  108
m/s.
Total internal reflection is achieved with a lower critical angle when the ratio between the
indices of refraction is greater.

5. Paul, a stationary observer, is sitting in the audience of a circus show. He sees two rolling
platforms moving along the same track. Both platforms are travelling at a constant speed
of 15 km/h in the same direction.
The first platform has two jugglers. The second platform, travelling behind the first, holds a
cannon which shoots foam balls at the jugglers. The cannon launches the balls at a speed
of 15 km/h.
At the same time, an acrobat moves horizontally on a cable at 30 km/h in the same
direction as the platforms.
The diagram below illustrates the circus show as seen by Paul.
Circus Show as Seen by Paul
Which of the following correctly states what Paul sees?
A) Paul sees the acrobat moving as fast as the cannon-fired foam balls.
B) Paul sees the jugglers moving as fast as the cannon-fired foam balls.
C) Paul sees the acrobat moving twice as fast as the cannon-fired foam balls.
D) Paul sees the jugglers moving twice as fast as the cannon-fired foam balls.
