What are the factors that cause a Travelling wave?
Surge is a type of travelling wave which is caused because of the movement of charges along the conductor. The surge generates because of a sudden vary steep rise in voltage (the steep front) followed by a gradual decay in voltage (the surge tail).
What does the frequency depend on?
The actual frequency is dependent upon the properties of the material the object is made of (this affects the speed of the wave) and the length of the material (this affects the wavelength of the wave).
What happens when you increase amplitude?
A sound wave’s amplitude relates to changes in pressure. The sound is perceived as louder if the amplitude increases, and softer if the amplitude decreases. As the amplitude of the sound wave increases, the intensity of the sound increases. Sounds with higher intensities are perceived to be louder.
Can you increase the amplitude of light?
You can. Decreasing its value is really easy: just make it pass through a partially absorbing filter. If you don’t mind if it changes polarisation, a polariser can be really useful.
How can you change the amplitude of the wave?
Amplitude is the size of the wave, or the vertical distance between its peak and it’s trough. Therefore, by making larger motions, you increase the amplitude. The other property is frequency, which is the distance from one peak/trough to the next. To increase frequency, you would shale the rope faster.
How do you increase the amplitude of a water wave?
The amplitude of the wave gets bigger as it gets squished. The frequency of the wave increases because the time it takes for the energy to hit the bottom and come back up is shorter, because the distance between the water surface and the bottom is shorter.
Does amplitude change with time?
A steady state amplitude remains constant during time, thus is represented by a scalar. Otherwise, the amplitude is transient and must be represented as either a continuous function or a discrete vector.
What happen if you increase the amplitude of oscillation?
When you increase the amplitude of a realistic pendulum, its period grows (frequency decreases) and the oscillation are no longer sinusoidal. If we would increase the energy of the pendulum any further by moving it up to the top and giving it an additional push, it would start to rotate.
