The figure shows waves traveling on two strings. Each string is attached to a wall at one
Question:
(i) Is the tension the same in each string?
(ii) Is the speed of each wave the same?
(iii) String 1 has a smaller mass and, hence, less inertia than string 2. Does this mean that the speed of the wave on string 1 is greater than the speed on string 2? Calculations: Determine the speed of the wave on each string.
One of the most important concepts we encountered in this chapter is the transverse wave. For instance, transverse waves travel along a guitar string when it is plucked or along a violin string when it is bowed. Problem 112 reviews how the travel speed depends on the properties of the string and on the tension in it. Problem 113 illustrates how the Doppler effect arises when an observer is moving away from or toward a stationary source of sound. In fact, we will see that it's possible for both situations to occur at the same time.
