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't 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 'describe' or 'explain'. They will be written in the form of a question like 'What…?' or 'Why…?'.

There will be more multiple choice questions on the Foundation paper.

Sample question 1 - Foundation

Question

Seismic (earthquake) waves can be either P-waves or S-waves.

Which row of the table is correct for P-waves? [1 mark]

Tick one box.

Type of waveCan they be refracted?
ALongitudinalYes
BTransverseNo
CLongitudinalNo
DTransverseYes
Type of waveCan they be refracted?
ALongitudinalYes
BTransverseNo
CLongitudinalNo
DTransverseYes

P-waves are longitudinal, all waves can be refracted.

Sample question 2 - Foundation and Higher

Question

The diagram below shows a transverse wave:

Transverse wave diagram. A wavy red line with two humps on each side of a horizontal line. A vertical arrow is in the first hump above the line and a horizontal arrow across  the two peaks underneath.

a) Use the words shown below to label the distances X and Y. [2 marks]

amplitude, frequency, magnification, speed, wavelength

b) Q is a particle in the wave.

4 graphics showing dots with arrows extended from them, labelled A B C and D. A is two arrows up and down. B is two arrows up and right. C is a left arrow and D is a right arrow.

Which of these shows the way in which particle Q moves? [1 mark]

a)

  • X = amplitude [1]
  • Y = wavelength [1]

b) A [1]

Sample question 3 - Higher

Question

This figure shows a ripple tank which is used to study the behaviour of water waves:

A ripple tank, on a table, with surrounding equipment including a lamp, power supply, motor and wooden beam supported by elastic bands.

Water waves are produced in the tank. The shadow of the waves is projected onto the screen below the tank. The waves appear to move in the direction of the arrow. The screen is 80 cm long.

a) What is the approximate wavelength of the waves as seen on the screen? [1 mark]

Tick one box.

A4 cm
B8 cm
C40 cm
D80 cm

b) A student uses the image to estimate the speed of the water wave as 75 cm/s.

Which of these is a reason why the estimate is not correct? [1 mark]

Tick one box.

AThe student used a ruler without mm markings
BThe light was not bright enough
CThe student's measurement was inaccurate
DThe wave seen on the screen is magnified

a)

A4 cm
B8 cm
C40 cm
D80 cm

Count the number of wavelengths shown on the screen. Calculate 80 ÷ number of wavelengths. There are 19 wavelengths, so 80 ÷ 19 = 4.21 cm. The question asks for the approximate wavelength. When rounded to the nearest cm, the answer is 4 cm.

b)

AThe student used a ruler without mm markings
BThe light was not bright enough
CThe student's measurement was inaccurate
DThe wave seen on the screen is magnified

The waves on the screen are larger than the waves in the water - they have been magnified.
