Hz as a unit of measurement is "cycles per second"
100 Hz is then 100 cycles of the oscillation per second.

A 100 Hz wave has a frequency of 100 vibrations per second. This means that the wave completes 100 back-and-forth movements in one second.
The speed of a wave is calculated by multiplying its wavelength by its frequency. Therefore, the speed of the wave with a 0.2 Hz wavelength and 100 meters frequency would be 20 meters per second (0.2 Hz * 100 meters = 20 m/s).
To find the speed of the wave, you can use the formula: speed = frequency x wavelength. Given the frequency is 0.2 Hz and wavelength is 100 meters, you can calculate the speed of the wave as 0.2 Hz x 100 meters = 20 meters per second.
The period of a wave is the time it takes for one complete cycle to pass a point. It is inversely proportional to frequency, so the period can be calculated as the inverse of the frequency: 1/100 Hz = 0.01 s. The wavelength does not affect the period of the wave.
The speed of the wave can be calculated using the formula speed = frequency x wavelength. In this case, the frequency is 5.0 waves per second and the distance between wave peaks (wavelength) is 20 cm. Therefore, the speed of the wave is 5.0 waves/s x 20 cm = 100 cm/s.
The frequency of the wave is equal to the speed of the wave divided by the wavelength. In this case, the frequency would be 10 Hz.
