Period = reciprocal of frequency = (1/9) = 0.111 second (rounded, repeating)

frequency
frequency
That is frequency.
Period = (1) divided by (frequency) = (wavelength) divided by (speed)Frequency = (1) divided by (period) = (speed) divided by (period)Speed = (wavelength) times (frequency) = (wavelength) divided by (period)Wavelength = (speed) divided by (frequency) = (speed) times (period)
0.25
frequency
The frequency increases.
That is frequency.
frequency
Period = (1) divided by (frequency) = (wavelength) divided by (speed)Frequency = (1) divided by (period) = (speed) divided by (period)Speed = (wavelength) times (frequency) = (wavelength) divided by (period)Wavelength = (speed) divided by (frequency) = (speed) times (period)
The frequency and period of a wave are inversely proportional. Therefore, as the frequency increases, the period decreases. frequency = 1/period period = 1/frequency
The phrase "the number of waves passing a point each second" is a definition of frequency.So if that number increases, then the frequency increases, by definition.
That means that the frequency increases. In that case, and assuming the speed of the wave doesn't change, the wavelength gets shorter. The general rule is: frequency x wavelength = speed (of the wave)
hertz
That is called the frequency of the wave.That is called the frequency of the wave.That is called the frequency of the wave.That is called the frequency of the wave.
