Effects of depth on the propagation velocity of water waves (The…

- - - - Water Depth
        
        We have considered the values of 2 cm, 3 cm, 4 cm, 5 cm and 6cm for the depth of water in the tray. For each we have done three trials.
    - - Wave Speed
        
        We have focused on measuring the time [+/-0.01s] taken by a water wave to travel the length of the tray to one side and back [+/-0.1cm].
        Wave speed is given by the ratio of the wavelength [+/-0.1cm] and the time taken for it to cover that distance [+/-0.01s].
    - - Wave to consider - Water temperature - Wave to consider - Dropping Height: 7cm - Water Tray
  - - - The waves will go slower when there is less water because they are more affected by friction with the tray, causing them to slow down. When instead there is more water the waves will be less affected by friction with the tray, increasing the wave speed.
  - - - Fill the container with tap water;
      - prepare the water tray on a flat and stable desk;
      - fix one ruler to the tray’s side, aligning its lower border with the 0 cm sign of the ruler;
      - fix the other ruler to the side of the desk in order to sign 7 cm from its start;
      - fill the tray with water until it reaches the 2 cm sign;
      - start recording with the phone on the tray’s side;
      - pull the tray up to 7 cm and drop it on the desk;
      - wait until the waves created hit the side opposite from the one you are standing in front of, and start the chronometer;
      - stop the chronometer when the waves hit the opposite side again;
      - stop recording;
      - repeat this process 2 more times with the same amount of water;
      - repeat steps 5-11 but with the different amounts of water (3,4,5,6) cm.
