FAQ

Those interested in the Travelling wave vs standing category often ask the following questions:

☑️ How does standing wave differ from travelling wave?

In that its polarity will not shift.

☑️ What is a travelling wave and a standing wave?

  • Travelling waves transport energy from one area of space to another, whereas standing waves do not transport energy. Also, points on a standing wave oscillate in phase, whereas on a travelling wave only points a wavelength apart oscillate in phase - the rest on that wavelength oscillate out of phase with the original point.

☑️ What's the difference between a standing wave and a travelling wave?

  • A travelling wave moves from one place to another, whereas a standing wave appears to stand still, vibrating in place. In this animation, two waves (with the same amplitude, frequency, and wavelength) are travelling in opposite directions. Using the principle of superposition, the resulting wave amplitude may be written as:

☑️ How to tell if a wave is standing or travelling?

If the function don't obey the wave equation, this means that is not a wave. Every time that you can separate the x and t such that at final you have f(x)g(t), you have a standing wave. Note that f(x)g(t)+h(x)s(t) is not a stading wave in general.

☑️ How are standing waves different from travelling waves?

  • Since adjacent points are in phase, no energy is transferred from one point to the next, unlike a travelling wave. Standing waves are formed by the superposition of two travelling waves of the same frequency (with the same polarisation and the same amplitude) travelling in opposite directions.

Why only standing wave makes sound wave?

In musical instruments, a standing wave can be generated by driving the oscillating medium (such as the reeds of a woodwind) at one end; the standing waves are then created not by two separate component waves but by the original wave and its reflections off the ends of the vibrating system…

It means that each point of the wave has a constant amplitude - but the amplitude is not the same for all points. Certain points where the wave passes - the nodes - have ZERO amplitude.This usually happens when the wave interferes with itself, for example, when the wave is reflected and goes back and forth.

Why standing wave ratio will happens?

Standing Wave Ratio is the ratio of the maximum and minimum amplitudes of a standing wave in a transmission line. It happens because of an impedance mismatch--trying to use a 75-ohm television antenna with a 50-ohm CB radio, for instance. The signal can't cleanly transfer from the cable to the antenna and some of it reflects back to your radio.SWR has two bad effects. One is it wastes transmitting power. If you are transmitting at 1000 watts and you have 3dB reflecting back to the amplifier, you're only putting 500 watts on the air. The other is the damage it can do to your radio, if you have a solid state amplifier--transistors don't like to dissipate 500 watts of power. It ain't real good for your tube amp either, but high SWR will cook a solid state amp.
