2. The distance between two consecutive crests or troughs of a wave is called the:
Amplitude
Frequency
Wavelength
Period
3. Waves transfer from one place to another without transferring .
4. The of a wave is the number of complete oscillations per second, measured in Hertz (Hz).
5. Describe the difference between a transverse wave and a longitudinal wave. Provide an example of each.
