  • Q7
    If the pitch of a sound wave is increased, does the time period between waveforms increase or decrease?
    Increases
    Remains the same
    Randomly changes to a discrete value
    Decreases

  • Q8
    A car horn produces a sound wave of frequency 680Hz. When the sound wave is travelling through air, it has a wavelength of 0.5m. What is the speed of the sound wave?
    330m/s
    400m/s
    300m/s
    340m/s
    30s
  • Q9
    The car horn and car unfortunately find themselves under water in a river. The car horn still produces a sound wave with a frequency of 680Hz, however the speed of the sound is dramatically increased to 1485m/s. What is the wavelength of the sound wave in water?
    1,009,800m
    2.18m
    0.92m
    0.46m

  • Q10
    What is an ultrasound wave?
    There are no such things as ultrasound waves
    Ultrasound waves are transverse waves
    An ultrasound wave is a sound wave which has the same frequency as an audible sound wave, however it has much greater energy
    An ultrasound wave is a sound wave which has a frequency higher than 20kHz
