QUESTION 6 Mаke sure tо hаve the Imаge PDF. ready fоr this questiоn. 6.1 A student investigates a sound wave with a frequency of 25 000 Hz. Calculate the wavelength of this sound wave. Round off your answer to three decimal places. [speed of sound = 330 m/s] (4) 6.2 The oscilloscope trace represents the sound wave. Refer to the Image PDF. for the oscilloscope trace. 6.2.1 Determine the amplitude of the oscilloscope trace. (2) 6.2.2 Diagram 1 (on the image PDF.) shows a coil of wire wrapped around a cardboard tube. The coil is fixed to the cardboard tube. Copy diagram 1 and draw field lines to represent the magnetic field produced when the current is in the direction shown. (3) 6.2.3 Diagram 2 (on the image PDF) shows a model of a loudspeaker that uses the coil and the cardboard tube. The cardboard tube is fixed to a thin piece of card, which is clamped at both ends. The student holds a bar magnet near the bottom of the cardboard tube. Explain why this causes the loudspeaker to produce a sound. (3) 6.2.4 When the frequency of the alternating current is 10 kHz, the student hears a sound. The student increases the frequency of the alternating current to 25 kHz. Explain why the student cannot hear a sound now, even though the card is still vibrating. (2) 6.2.5 Suggest a change to the apparatus that would increase the loudness of the sound when the frequency of the alternating current is 10 kHz. (1) 6.3 X-rays have a speed of 3.00 × 108 m/s in air. Calculate the wavelength of these x-rays. (3) TOTAL QUESTION 6: [18] GRAND TOTAL: [70]
