Waves in fluids- Required practical

• You can determine wave speed ,frequency and wavelength of waves by using appropriate apparatus.
• Practical - waves in fluids

  -

  Aim - to investigate the suitability of apparatus to measure the speed , frequency and wavelength of waves in a fluid .

  -

  Apparatus:

  1. Ripple tank
  2. Motor
  3. Plane wave generator
  4. Stroboscope
  5. ruler
  6. A3 paper
  7. Pencil


  Method:

  1. Set up the apparatus
  2. Calculate the frequency of the waves by counting the number of waves passing a point each second
  3. Do this for 1 minute and divide by 60 for a accurate frequency of water waves.
  4. Use a stroboscope to “ freeze “ the waves and find their wavelength using a ruler -this can be projected onto a3 paper
  5. Calculate wave speed
• Water waves will travel at a constant speed in a ripple tank when generated at different frequencies if the depth of the water is constant at all points.
