Frequency
7 hertz. Since frequency of the wave motion is defined as the number of waves ie number of wavelengths crossing a particular point in the medium in one second.
...frequency.That's called the wave's frequency. Often measured in Hertz (Hz).
2 Hz is.
Yes.
Frequency is the number of waves per second, i.e. 20Hz is 20 waves per second. Wavelength is obviously the length of each wave i.e 20m So if there are 20 waves per second, the distance it travels is the length of the wave multiplied by the number of waves in one second. The distance travelled in one second by the wave above is therefore 20 * 20m wich is 400m. The distance travelled in 1 second is 400m. Therefore every second, the wave travels 400m and thus the speed is 400meters per second (400m/s).

Frequency.
That's called the frequency.
No. The crest is the height of the wave. The period is the time it takes for 2 waves to pass one point. ---Only one wave, but two crests, the high and the low one. The number of waves per second is the frequency. Sage.
One Second.
