WebWaves on strings combine linearly. This means that you can split up a string's motion into two (or more) superimposed waves. The two superimposed waves behave independently, as if the other one was not there. So if you have a standing wave set up on a string, and then you also introduce a travelling pulse, you get something like the following. WebA periodic wave is a wave with a repetitive pattern that extends in the whole space, while a wave packet has a non-vanishing amplitude in a certain region of space. A stationary wave is the result of the superposition of two waves with the same frequency travelling in opposite directions. It does not have a global speed, unlike progressive waves.

WebIn this type the derivative (slope) of the wave's amplitude (in sound waves the pressure, in electromagnetic waves, the current) is forced to zero at the boundary. So there is an amplitude maximum (antinode) at the boundary, the first node occurs a quarter wavelength from the end, and the other nodes are at half wavelength intervals from there: WebThe resultant displacement at each point is maximum. The particle velocity is zero but the strain is maximum possible. At t = 4T/4 s, the incident and reflected waves at each point are in the opposite phases. The strain ∆y/∆x at each point is zero. At points N1, N2, N3 and N4, the amplitude is zero but the strain is maximum. WebIn a stationary wave strain is maximum at the node because two opposite forces act at the node. What factors affect the frequency of a wave on a string? The four properties of the string that affect its frequency are length, diameter, tension, and density. highest rated driftwood laminate floor
