4. Water Waves The type of water waves we are studying in Activity 4 are caused by a disturbance (earthquake or ice falling in water, or a pebble in a pond for a small wave)The type of water waves we are studying in Activity 4 are caused by a disturbance (earthquake or ice falling in water, or a pebble in a pond for a small wave) Normal waves are caused by the tides (gravitational pull of the moon) and wind.Normal waves are caused by the tides (gravitational pull of the moon) and wind.

20. 150 Hz 300 Hz 600 Hz 150 Hz

21. The 150 Hz sound has the lowest frequency and the longest wavelength. The 600 Hz sound has the highest frequency and the shortest wavelength.  Wavelength  Frequency/  Pitch,  Wavelength

22. Buzzer video

23. bell jar video

24. When the air is removed from the jar, there is no sound heard from the buzzer. This is because there is no medium for the compression wave to travel in. Mechanical waves require a medium to travel in!
