Waves in 2D

  1. What are surface waves? State their properties with example.
  2. Does water move out with the ripple as the wave passes? Explain mathematically.
  3. Which kind of velocity of wave is observed in this experiment – particle velocity, phase velocity or group velocity? Explain your answer in brief.
  4. Express the velocity in terms of surface tension force at the regime of the “true ripples”?
  5. What does a negative velocity signify in this experiment?
  6. What do you understand by “strobe frequency” and “vibrator frequency”? Comment briefly on the synchronous and independent modes of the vibrator.
  7. What happens if we use liquid other than water to carry out the experiment?
  8. Is this experiment good enough to comment on the wave nature of light?
  9. What do you think will differ in your observation if the water level is increased drastically?
  10. Is it possible to create standing wave pattern using this instrument? If yes, explain the conditions.
