Answer:
Wave 1: 2
Wave 2: 3
Wave 3: 1
4: wave 2 has the highest frequency
5: wave 3 has the lowest frequency
6: definition of frequency: the rate at which a vibration occurs that constitutes a wave, either in a material (as in sound waves), or in an electromagnetic field (as in radio waves and light), usually measured per second.
7: the way to tell if a wave has high frequency is by it have a lot more hill-like waves
And a low frequency wave has low and long hills
