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. The cork initially has some potential energy when it is held above the water—the greater the height, the higher the potential energy.
Learn about how waves are measured according to amplitude, wavelength and frequency.
Use the wave equation to find the velocity of the resulting wave: $$\begin{split} \frac{\partial^{2} y(x,t)}{\partial x^{2}} & = \frac{1}{v^{2}} \frac{\partial^{2} y(x,t)}{\partial t^{2}}, \\ -Ak^{2} \sin (kx - \omega t) + 4Ak^{2} \sin(2kx + 2 \omega t) & = \frac{1}{v^{2}} \left(-A \omega^{2} \sin (kx - \omega t) - 4A \omega^{2} \sin(2kx + 2 ...
In National 4 Physics examine the properties of waves and use the wave equation, v = f λ, to relate the speed, frequency and wavelength.
This leads us to one of the most important formulas you will use when studying waves. Frequency tells us how many waves are passing a point per second, the inverse of time. Wavelength tells us the length of those waves in metres, almost like a displacement.
17 Αυγ 2023 · For a simple sinusoidal wave, the amplitude can be calculated using the following formula: A = (y_max - y_min) / 2. Where: – A is the amplitude of the wave – y_max is the maximum displacement of the wave – y_min is the minimum displacement of the wave.
