Chapter 16: Q. 7 (page 451)

Draw the snapshot graph D (x, t = 1.0 s) at t = 1.0 s for the wave shown in FIGURE EX16.7.

Short Answer

Expert verified

The snapshot graph of the wave is shown.

Step by step solution

01

Write the given information

The history graph of the wave is given at distance x= 0 m
The velocity of the wave is given as v = 1 m/.sec
The wave is traveling to the left.

02

 Step 2: To draw the snapshot graph of the wave at time t= 1.0 sec

A snapshot graph shows the displacement of the wave with respect to the position at a given time and a history graph shows the displacement of the wave with respect to the time at a given position.

Analyze the history graph

  • With every second, the wave travels 1-meter to the left
  • In 6 seconds, the wave would travel 6-meters

The snapshot graph is shown below.

Figure Q16.3 is a history graph showing the displacement as a function of time at one point on a string. Did the displacement at this point reach its maximum of 2 mm before or after the interval of time when the displacement was a constant 1 mm?

Your ears are sensitive to differences in pitch, but they are not very sensitive to differences in intensity. You are not capable of detecting a difference in the sound intensity level of less than 1 dB. By what factor does the sound intensity increase if the sound intensity level increases from 60 dB to 61 dB?
