5 A lоudspeаker prоduces а sоund wаve in air. (a) Diagram 1 shows air molecules before the sound wave passes. See addendum Question 5, Fig.5.1 At a particular instant as the sound wave passes, the air molecules are displaced as shown in Diagram 2. See addendum Question 5, Fig.5.2 (i) Label a point on Diagram 2 where the pressure of the air is a minimum. (1) (ii) Sketch a graph of displacement against distance for the air particles between A and B at this instant on the axes below. (2) See addendum Question 5, Fig.5.3 (b) The speed of sound can be determined using the apparatus shown. See addendum Question 5, Fig.5.4 When the loudspeaker is switched on, two traces are produced on the oscilloscope, one directly from the signal generator and the other from the microphone. (i) Describe how a value for the speed of sound in air can be determined. (4) (ii) Describe how the oscilloscope display can be used to demonstrate that the two traces have the same frequency. (2) (iii) A frequency of 15.0 kHz was used. A student suggested that the experiment would give a more accurate result for the speed of sound if a frequency of 4.0 kHz was used. Evaluate the student's suggestion. You should use a calculation in your answer. speed of sound in air = 340 m s−1 (3) (Total for question 5 = 12 marks)
