Multiple choice questions
Multiple choice questions are perhaps the easiest to complete, you simply put a cross in a box. However, the questions often have two answers that could, at first glance, be correct. Don鈥檛 make the mistake of reading the first answer and thinking this is correct without checking all the others.
If it says 'Tick one box', you must tick one box. If you leave it blank or tick two or more boxes, you will get zero marks. These multiple choice questions will not start with command words like 鈥榙escribe鈥 or 鈥榚xplain鈥. They will be written in the form of a question like 鈥榃hat鈥?鈥 or 鈥榃hy鈥?鈥.
There will be more multiple choice questions on the Foundation paper.

Sample question 1 - Foundation
Question
The figure below shows an incomplete electromagnetic spectrum.
| A | microwaves | B | C | ultraviolet | D | gamma |
| A |
| microwaves |
| B |
| C |

| D |
| gamma |
What name is given to the group of waves at the position labelled A in the figure above? [1 mark]
Tick one box.
| A | infared | |
| B | radio | |
| C | visible light | |
| D | X-ray |

Radio waves have the longest wavelengths and the lowest frequencies of all the electromagnetic waves. Gamma waves have the shortest wavelengths and the highest frequencies.
Sample question 2 - Foundation
Question
Small water waves are created in a ripple tank by a wooden bar. The wooden bar vibrates up and down hitting the surface of the water.
The figure below shows a cross-section of the ripple tank and water.
Which letter shows the amplitude of a water wave? [1 mark]
Tick one box.
| A | J | |
| B | K | |
| C | L |

The amplitude of a wave is measured between a peak and the rest position as shown by arrow K. Arrow J shows twice the amplitude and arrow L shows the maximum depth of the water.

Which of the waves, A, B or C is an infrared wave? [1 mark]
C
Infrared waves are slightly longer than visible light waves. B is a microwave and A is a radio wave.
