Many of the topics discussed in this chapter are useful beyond the topics of mechanical waves. It is hard to conceive of a mechanical wave with sharp corners, but you could encounter such a wave form in your digital electronics class, as shown below. This could be a signal from a device known as an analog to digital converter, in which a continuous voltage signal is converted into a discrete signal or a digital recording of sound. What is the result of the superposition of the two signals?
A pulse is defined as y(x,t)=e2.77( 2.00( x2.00m/s ( t ) ) 5.00m)2 . Use a spreadsheet, or other computer program, to plot the pulse as the height of medium y as a function of position x. Plot the pulse at times t=0.00s and t=3.00s on the same graph. Where is the pulse centered at time t=0.00s ? Use your spreadsheet to check your answer.
(Indicates a review question, which means it requires only a basic understanding of the material to answer. Questions without this designation topically require integrating Or extending the concepts presented thus far.) What is the difference between a longitudinal wave and a transverse wave? Give an example of each.
Consider two wave functions y1(x,t)=Asin(kxt) and y2(x,t)=Asin(kx+t+) . The resultant wave form when you add the two functions is yR=2Asin(kx+2)cos(t+2) . Consider the case where A=0.03m1,k=1.26m1,=s1 , and =10 . (a) Where are the first three nodes of the standing wave function starting at zero and moving in the positive x direction? (b) Using a spreadsheet, plot the two wave functions and the resulting function at time t=1.00 s to verify your answer.
A certain uniform string is held under constant tension. (a) Draw a side-view snapshot of a sinusoidal wave on a siring as shown in diagrams in the text. (b) Immediately below diagram (a), draw the same wave at a moment later by one-quarter of the period of the wave. (c) Then, draw a wave with an amplitude 1.5 times larger than the wave in diagram (a). (d) Next, draw a wave differing from the one in your diagram (a) just by having a wavelength 1.5 times larger. (e) Finally, draw a wave differing from that in diagram (a) just by having a frequency 1.5 times larger.
What is the source of wave pulse? How do you describe the motion of your hand, as you create the pulse? How do you describe the motion of the pulse, with respect to the source?
What is a mechanical wave? What does a wave do? Based on their motions waves can be classified as one of two types. What are these two classifications and what are the relevant motions for each? What is sound? What aspect of a sound wave indicates how loud the sound is? What happens when you move away from the source of the sound? What quantity is involved in calculating this effect? What determines the speed of a sound (or any mechanical) wave?
