Amplitude—distance between the resting position and the maximum displacement of the wave. Frequency—number of waves passing by a specific point per second. Period—time it takes for one wave cycle to complete. In addition to amplitude, frequency, and period, their wavelength and wave velocity also characterize waves.
Since wave frequency is the number of waves per second, and the period is essentially the number of seconds per wave, the relationship between frequency and period is f = 1 T 13.1
How are amplitude, period, and phase shift related?
The Period goes from one peak to the next (or from any point to the next matching point): The Amplitude is the height from the center line to the peak (or to the trough). Or we can measure the height from highest to lowest points and divide that by 2. The Phase Shift is how far the function is shifted horizontally from the usual position.
Which is the correct formula for amplitude and period?
In words: the 2 tells us it will be 2 times taller than usual, so Amplitude = 2. the usual period is 2π, but in our case that is “sped up” (made shorter) by the 4 in 4x, so Period = π/2.
Is the amplitude of a wave affected by an earthquake?
No, only the amplitude is affected. Yes, the wavelength is affected. Students can measure the bowl beforehand to help them make a better estimation of the wavelength. Figure 13.9 The destructive effect of an earthquake is a palpable evidence of the energy carried in the earthquake waves.
Is the amplitude X independent of the speed of propagation?
The amplitude X is completely independent of the speed of propagation vw and depends only on the amount of energy in the wave. In this lab, you will take measurements to determine how the amplitude and the period of waves are affected by the transfer of energy from a cork dropped into the water.
How are amplitude and speed of water waves related?
These fundamental relationships hold true for all types of waves. As an example, for water waves, vw is the speed of a surface wave; for sound, vw is the speed of sound; and for visible light, vw is the speed of light. The amplitude X is completely independent of the speed of propagation vw and depends only on the amount of energy in the wave.
