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