Questions and Answers

What is the formula for calculating the frequency of a wave?

  • Frequency = wavelength * amplitude
  • Frequency = energy/time
  • Frequency = number of waves/time (correct)
  • Frequency = speed/distance

    • What is the relationship between sound intensity and distance from the source?

  • The intensity of sound varies linearly with the distance from the source
  • The intensity of sound varies directly with the distance from the source
  • The intensity of sound is independent of the distance from the source
  • The intensity of sound varies inversely with the square of the distance from the source (correct)

    • Which range of frequency corresponds to ultrasound?

  • Above 20,000 Hz (correct)
  • 20 Hz to 20,000 Hz
  • 20 Hz to 20,000 kHz
  • Below 20 Hz
