Given a wave f(x, t), we call period T the interval of time we need to wait before the form of the wave is repeated. Obviously, we must choose a constant x and observe the wave passing trough it.
For exemple, for f(x, t) = ei(kx - wt) it's f(x, t + T) = ei(kx - w(t + T)), so that we have 0 = f(x, t + T) - f(x, t) = ei(kx - wt) (e-iwT - 1) → e-iwT = 1 → T = n 2π/w, with n element of Z. If we are considering two near peaks of f (that is a good way to define T) n = 1, and we have the famous T = 2π/w.
Wave frequency f, and period of wave T are inverses, related by fT=1.
Just divide the wavelength by the wave period, and you've got the wave speed.
Period = 1 / frequency
Period = 1/78.6 seconds = 0.01272 seconds
The period of a wave is defined as the time taken by a wave to complete one oscillation. While, the frequency of a wave is defined as the number of oscillations completed by a wave in one second.
A wave length.
The reciprocal of the period of ANY wave is the wave's frequency.
Wave period can be found by dividing the wavelength by the wave speed. The formula is: Period = Wavelength / Wave Speed. The period represents the time it takes for one wave cycle to pass a given point.
Wave speed is dependent on both wavelength and period. The relationship is described by the formula: wave speed = wavelength / period. As wavelength increases, wave speed also increases. Conversely, as period increases, wave speed decreases.
When a wave period decreases, speed increases.
Wave frequency f, and period of wave T are inverses, related by fT=1.
True. The period of a wave is inversely proportional to its frequency. That means as the frequency of a wave increases, the period of the wave decreases proportionally.
Just divide the wavelength by the wave period, and you've got the wave speed.
Period = 1 / frequency
When you decrease the wave period, the wavelength becomes shorter and the frequency increases. This results in the wave moving faster.
Period = 1 / frequency
When the period of a wave decreases, the frequency of the wave increases. This is because frequency and period are inversely related - as one increases, the other decreases. So, a shorter period corresponds to a higher frequency.
