QUESTION 1 What type of wave are sound waves? Longitudinal wave Transverse wave QUESTION 2 A bottle has 33.5 liters in volume, how many cubic meter is it? QUESTION 3 A sound wave makes 15 cycles per 3.54 seconds. What is the frequency in Hz? QUESTION 4 A sound wave has a period of 5.49 seconds. What is the frequency in unit of Hz? QUESTION 5 A wave has a period of 0.0002763981 seconds and a wavelength of 119.85 cm. What is the velocity of the wave in m/s? QUESTION 6 What is the speed of sound in air under normal conditions in m/s?

Explanation / Answer

1) Sound waves are longitudinal waves, because the particle motion is parallel to direction of propagation of wave.

2) 1 litre = 0.001 cubic meters, so 33.5 litres = 0.0335 cubic meters.

3) 15 cycles per 3.54 sec equals 4.2373 cycles per second, so frequency is 4.2373 Hz.

4) T = 5.49 sec, so frequency f = 1/T = 1/5.49 = 0.182 Hz.

5) The velocity of wave is V = L/T = 1.1985 m / 0.0002763981 sec = 4336.137 m/sec.

6) Speed of sound in air in normal conditions is 343 m/sec.

7) Percentage difference is [(69.4 - 63.7) / 69.4] x 100 = 8.213 %.

8) 25 cm = 0.25 m or 1/4th meter.

9) This cannot be answered without knowing what is used in lab.

10) The zoom in option can be used by the button 'B'.
