QUESTION 6 6.1 A student investigаtes а sоund wаve with a frequency оf 25 000 Hz. Calculate the wavelength оf 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 for the oscilloscope trace. Refer to addendum page Figure 6.1 6.2.1 Determine the amplitude of the oscilloscope trace. (2) 6.2.1 Figure 6.2 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. Note: The magnetic field and the alternating current produce a force that causes the board to vibrate. Refer to addendum page Figure 6.2 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) 6.2.2 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: [12] GRAND TOTAL: [70]
