Examples of waves[change | change source]
- electromagnetic spectrum including
- water waves such as ocean surface waves
- earthquake waves
All of these waves are sums of sine waves.
"Length" of a sine wave[change | change source]
The sine wave has a pattern that repeats. The length of this repeating piece of the sine wave is called the wavelength. The wavelength can be found by measuring the length or distance between one peak of a sine wave and the next peak. The wavelength can be found in many other ways too.
