Revision: Sound 13 Sound - Revision Quiz Test your understanding of Sound here: 1 / 5 1) The following shows the displacement-distance graph for a wave. What is the wavelength of the wave? 0.30 m 3.5 m 0.29 m 0.33 m 2 / 5 2) 2018 S4 EOY P1 Q16 A sound wave has a frequency of 2.5 × 104 Hz. This wave cannot be heard as it is in the infrasound region. This wave can be heard as it is in the audible region. Whether it can be heard or not will depend on the quality of the note. This wave cannot be heard as it is in the ultrasound region. 3 / 5 3) Bees which are not carrying pollen fly with a flapping frequency of 440 Hz while those which are carrying pollen fly with a flapping frequency of 300 Hz. The sound made by bees which are not carrying pollen has a lower pitch. is louder. has a higher pitch. is softer. 4 / 5 4) Ships use sound waves to find the vertical distance to the seabed. A pulse of sound waves is sent out and echoes are detected. A ship emits a pulse of waves lasting 0.50 s. The waves have a frequency of 3600 Hz. How many complete wavelengths does the pulse contain? 18 000 7200 3600 1800 5 / 5 5) The following is a displacement-distance graph for a wave. What is the amplitude of the wave? 12.0 m 6.0 m 3.4 m 1.7 m Your score is Restart quiz
