Question 5
Graphs representing two sound waves are given in Fig. 10.30. If the scales on the X and Y axes of the two graphs are the same, which of the two sound waves has (i) greater wavelength, and (ii) smaller amplitude?
View Answer Hide Answer
  • (i) The wave with crests spaced farther apart has the greater wavelength .
  • (ii) The wave whose curve rises and falls less from the average line has the smaller amplitude .
Reading Two Graphs Wider crest spacing means greater wavelength Smaller rise from average means smaller amplitude Compare the two curves
