Question

Suppose that the left-traveling pulse in Exercise 15.32 is below the level of the unstretched string instead of above it. Make the same sketches that you did in that exercise

Short answer

The sketches are shown below.

Step-by-step solution

Identification of the given data

The given data can be listed below as,

• The given times are, \(t = 0.250\;{\rm{s}},\,t = 0.500\;{\rm{s}},\,t = 0.750\;{\rm{s}},\,t = 1.000\;{\rm{s}},\,t = 1.250\;{\rm{s}}\).

Significance of the principle of superposition

According to the superposition principle, the total disturbance caused by two or more waves overlapping in space equals the algebraic sum of the individual disturbances.

Determination of the sketches

During their overlap, the pulses interfere with one another, but once they have completely gone through one another, they take on their original shape.

The figure below shows the string's shape at each designated period,
