- 1TRUE OR FALSE : Sound waves can travel at different speeds.TRUE, because temperature and the medium its going through affects the speed.
- 2TRUE OR FALSE : Frequency changes when wavelengths change.TRUE, because the frequency of a sounds depends on the wavelength. When the wavelength changes that means there are either more or less vibrations per second.
- 3TRUE OR FALSE : Pitch changes when frequency increases.TRUE, because the pitch is the assigned note our brain gives a certain frequency.
- 4TRUE OR FALSE : Speed of sound changes when wavelength increases.FALSE, wavelengths are irrelevant when measuring the speed of sound. (r x t = d)
- 5TRUE OR FALSE: Amplitude changes when frequency decreases.FALSE, loudness is not at all affected by frequency.
- 6TRUE OR FALSE : Amplitude changes when energy increases.TRUE, there is more energy behind the sound wave, making it louder.
- 7TRUE OR FALSE : Wavelengths change when energy increases.FALSE, loudness does not effect pitch.
- 8TRUE OR FALSE : Pitch changes when energy decreases.FALSE, because pitch relies on wavelengths (vibrations per second) not amplitude.
- 9TRUE OR FALSE : Frequency changes when energy decrease.FALSE, because each frequency is its own set amount or Hertz, or v/s. It does not depend on loudness.
- 10TRUE OR FALSE : Speed of sound changes when the sound maker is in motion.FALSE, because motion does not impact speed of sound (only weather and the substance its going through do)
- 11TRUE OR FALSE : Wavelength changes if the sound maker is in motion.TRUE, because motion disrupts the natural wavelengths of a set frequency. (shorter wavelengths in front, longer in back)
- 12TRUE OR FALSE : Frequency changes if sound maker is in motion.TRUE, change in wavelength causes a change in frequency.
- 13TRUE OR FALSE : Sound travels in transverse waves.FALSE, sound travels in longitudinal, or compressional waves.
- 14Natural Frequencythe frequency a sounds gives off without being tampered with
- 15decibel (dB)Unit of Amplitude, loudness
- 16Longitudinal WaveThe kind of waves sound travel in
- 17RarefactionChange in direction of waves
