    Image Upload 1
    Transverse
  3. Is this wave transverse or longitudinal?
    Image Upload 2
    Longitudinal
  4. Do ripples on water form a transverse or longitudinal wave?
    Transverse
  5. Do sound waves travel as longitudinal or transverse waves?
    Longitudinal
  6. Which type of wave oscillates parallel to the direction of travel?
    Longitudinal
  7. Which type of wave oscillates perpendicular to the direction of travel?
    Transverse
  8. What do all waves transfer, and what do they not transfer
    • They transfer energy,
    • without transferring matter
  9. What are the regions in a longitudinal wave called?
    • Compressions
    • Rarefactions
  10. What do the following letters represent?
    Image Upload 3
    • A: Crest (or peak)
    • B: Trough
    • C: Amplitude
    • D: Wavelength
  11. What wave quantity is defined as:
    "The number of waves passing a point each second"
    Frequency
  12. What is the unit of wavelength?
    metre
  13. What is the unit of frequency?
    Hertz (Hz)
  14. What is the equation linking wave speed, frequency and wavelength?
    chart?chf=bg,s,00000000&cht=tx&chl=v%20%3D%20f%5Clambda&chs=98x36
  15. Which of the following quantities is not changed when a wave moves from one medium to another?
    a) wavelength
    b) speed
    c) frequency
    Frequency
  16. Higher tier only
    What is the range of normal human hearing?
    20 Hz to 20 kHz
  17. Higher tier only
    What are seismic waves?
    Waves in the ground causes by earthquakes
  18. Higher tier only
    Which type of seismic wave can only travel through solids?
    S-wave
  19. Higher tier only
    Which type of seismic wave is transverse?
    S-wave
  20. Higher tier only
    Which type of seismic wave travels at different speeds in solids and liquids?
    P-wave
  21. Do light waves travel as longitudinal or transverse waves?
    • Transverse
    • (All electromagnetic waves are transverse)
  22. Higher tier only
    Describe how ultrasound waves are used to measure distance
    • A transducer emits ultrasound waves,
    • these are (partially) reflected from a media boundary
    • the transducer detects the reflected waves
    • the total distance travelled is calculated as s = v x t
    • the distance to the media is half of the total distance travelled (as it went there and back)
    • Image Upload 4
  23. Higher tier only
    What is echo sounding used for in water?
    Detect objects in deep water and measure water depth.
