SECTION A

For questions 1–10 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 .

2.Two waves from the same source arrive at a point with a path difference of 3 8 λ , where λ is the wavelength.

Which of the following is the phase difference of the waves at this point?

A 34°

B 68°

C 135°

D 270°

3.A diffraction grating has 300 lines per mm. When laser light is directed towards the diffraction grating, a diffraction pattern is observed on a screen. The position of a first order maximum on the screen is shown in the diagram.

Which of the following calculations should be used to determine the wavelength, in mm, of the laser light used?

4.Which of the following statements about physical quantities or units is correct?

A Current is a derived quantity.

B Power is a derived quantity.

C The coulomb is a base unit.

D The volt is a base unit

5.Ultrasound has a number of different uses in medicine.

Which of the following is the main reason why ultrasound is not used to perform scans of the chest and lungs?

A The air in the lungs causes most of the ultrasound to be reflected back.

B The duration of the pulses of ultrasound limits the amount of detail that can be seen.

C The wavelength of the ultrasound is too long.

D Ultrasound can damage the lungs.

6.Which electrical component has the current-potential difference graph shown?

A diode

B filament lamp

C resistor

D thermistor

7.A small metal cube, with sides of length x, is connected in a circuit. The current through the cube, between opposite faces, is I and the potential difference across the cube is V.

Which of the following gives the resistivity of the metal?

8.Which of the following statements about waves is correct?

A Both longitudinal and transverse waves can be polarised.

B Neither longitudinal nor transverse waves can be polarised.

C Only longitudinal waves can be polarised.

D Only transverse waves can be polarised.

9.Two copper wires are placed in series in a complete circuit. The electrons in the two wires have different values of drift velocity.

Which of the following must be different for the two wires?

A charge carrier density

B cross-sectional area

C current

D length

10.The circuit shows a potential divider, including a battery of negligible internal resistance and a light dependent resistor (LDR). The potential difference (p.d.) across the fixed resistor is measured using a voltmeter.

A If the resistance of the LDR halves, the voltmeter reading halves.

B Increasing the light intensity would decrease the voltmeter reading.

C Increasing the light intensity would have no effect on the voltmeter reading.

D The voltmeter reading added to the p.d. across the LDR will always be 12.0 V.
